Chests as reward with revamped system / or any other reward should be bringed into FF. Now it feels simply as non rewarding aspect of game.
Option 1 potential reward - Wooden, Iron,Steel along with Unique and Unique Precious. Hell even something like fortbattles bag (based on x-mas bags) would be cool as reward with some mix of rewards in him.) There would be % of players that would get random chest after battle, everyone would get the same chance to obtain it no matter dodge/aim/dmg.
Option 2 would be for InnoGames to make simply new unique chest only for chests similiar to Awesomia battle ones that would be dropping randomly with everyone getting some chance of getting it after battle.
Option 3 could be to just raise EXP up to 10k(for future lvl cap) and UPD reward up to max 50-100(from current 25) per battle so you atleast feel you got anything and know you can buy something nice in shop for it without problems.
Option 4 Any bonus % REWARD with some probability to drop.
Current battles are really hard for Attacking side to get people when you usually know the outcome (now after x-mas it got much worse with +2 cortinas on 200% more people) so it would give some motivation to more people to join both sides and atleast it wouldnt feel like 30+ minutes for 6k exp and 10 upd.
I think reward changes should come even if FF will get some formula changes/tower nerfs along with future upgrades, because forts in the end dont have that big of value anymore on its own and it needs to attract players somehow.
Battles in general as stated many times before needs rebalance with formula/bonuses.
Adventure would be really cool to get PvE mode with the bear as boss there (which was in testing no idea why it dropped i would take even the beta version which looked nice enough imho lol) so players can finish it once it appears in some quests much easier and with less toxicity.
Class balance well thats another topic.. too, much needed thing and it would bring some new fresh status for game if devs can bring something nice and usefull or atleast balanced it a little bit.
Duels honestly as dueller myself with active duel build except sometimes its really huge RNG i feel like its working as intended, so i dont see much need for change except maybe duel level which should go lower much faster for non duelling if nothing else.
So im really hoping something will change because it would be shame to let game die just because it didnt get properly updated which is much needed.
Have a nice day and wish you best.
