*Bit lengthy, ill sum it up best i can*
Not bad concept, but as to type, comes in to weigh in incentive that only is temporary lure as to type, really if someone maintains a defense and levels up to meet game level needs it works pretty swell, however like a long long timer like Super, it kind of is a back fire as while the target is to ensure players who end up using peaceful may just do that and never level up there war level and risking any of there assets those pose, and receive all the benfits of game leveling while protected.
To recap, if a new player starts, and goes for say peaceful 10, understandable that if they have say countries that would normally be put at risk to level up, though if they play the cards right they dont need to level past 2 to obtain those countries. So ofcourse if someone wants level 10 in defense(full game) they would need (unless defesive index which is mostly to high for a maintaining level maybe big dog such as Aries could handle, in which one might just get that vs the war levels and could just sit war level 0, with like 2000 defensive index) war level 6 which prones there empire other then the 1 countrie in secured mode possibly. So concluding in a new perspective yes someone can just get game level 10 and not have to risk a thing vs a player reaching 10 in full game, have countries that will be prone to attack, despite the index/population requirements being lower in full game still puts them at risk.
So if someone chooses peaceful, there is a good chance they may never do anything war related unless to a minimal scale to obtain countrys and never leave protection. Though if they choose full game, they will level up the war level risking there assets, and also have to maintain a higher risked defense likely. So it does put forth some valid ability to make a scare change, but let me explain long term situation.
Though my point is, Super is a higher war level already from what i have seen, though he uses his empire on peaceful based on how he has his stats/indexs set up. For a player like Him, its not a road he has to take for a time, but rather an option of what game level method he wants to use(based on his ability as a player). In this case, it is peaceful. While the incentive catoirs to the need of saying; a player who is peaceful yet DOES NOT partake in risking avabile assets based on war level, will recieve penalty for not risking there assets, but rather more based on a generic state of not only changing index variables, but also simple asking "Do you risk you assets in war? Yes or No" in which yes there is no penalty and is preffered option for higher levels, vs no, that punishs you for not risking the assets. Not bad overall as someone who risks there stuff shouldent be treated the same as someone who can type there fingers to 5 200m pop countrys and not have to worrie about a single thing ever.
Though however, what if said player, Super, has already taken the incentives that the game states offer (full game encourage war leveling, defense building) while meeting needs of peaceful gameplay, yet is still punished for the simple fact that the games state of full or peaceful determines wheather or not you risk your assets, in which regardless of anything the assets are still risked if above war level 3 and anything outsides of secured mode. Thats not essentailly a fair concept, as it conclusivly proves as a new time incentive to yank players out of protection zone into a war zone, only to be punished possibly for the long term not by war, but also the own game thats trying to push it!!!!! As to respond that peacful dident put all countrys in protection, did it? If not, then if one such as Super has a war level over 3, he should not be punished at all for having countrys that infact may be more at risk then projected countrys at full game with minimal/some defense vs peacful in which a war level player may not have heavy defense to support the index needs of the game level.
******************************************************************************
MAIN: Do not make a penalty for secured mode!!!!! There is a reason why you guys made fearless blue, that is apart of this concept and purpose that the game state cannot determine this penatly you guys are working with, such as punishing someone on fearless blue for using peaceful gamemode with a war level higher then 3!! I agree this is a good helpful concept, though dont make it biased and simple switch projected as its already conceptually broken. How broken? Super explained himself good, and see you tell why its purpose exists yes good, but really understand as (sometimes points dont get across easy) for somebody who already risks/utilized incentives offered by full game, why would they need to be punished for. Simply the problem isent the game state peaceful, but rather the war level protection that prohibits them, as just because one requires less active defense so to say but higher indexs still poses same risks, which penalized is a no goodie.
=Suggestion/idea: Not based on peaceful or full game states but war levels; for people who are 0,1,2 need penalty to scores always as these are the "fake" protections, also stronghold protections that can never be broken. While with fearless blue, and other war levels, the penalty should be none although at higher war levels, such as 6+ should give a score increase opposed to penalty. say player wants to ever level using other game state, has to risk everything just as much with less defense likely and actually more to risk since peaceful game state concludes you need more country + more population very likely less defense, A BIGGER RISK when you have higher war levels. Why punish them for this?=
point is more to risk, though if they are only war levels 3+. I believe its balanced in all rights, more, heavier populated, countrys with better indexs concluding to having a lighter defense vs fewer , lighter population, country maintaing a higher defense index with likely lower indexs. This is why i believe the key is not basing a score award on game states but rather war levels directly themselves. Note that as typed, secured mode should NOT by anymeans be penatly, simple enough to type. Fearless Blue exists for a reason, players should have all the right to have 1 happy place on 4 worlds they shouldent have to throw away for risk of a award they can only get every few months, at the least..
Consider reading some atleast

not really bad but kind of ranty but trying to hit a core point with the score, as to type.
