How bout bonuses for going undefeated in battles or especially in war .... 4 attacks and your done win lose or draw.... that's kind of lame.
I would also like to be able to look up any player to either attack or visit
How about a faction bonus or an ability after say at 50 levels to add 2 upgrades at one time or build two buildings at one time .... Like a reward for leveling up or maybe even a special unit for that... throw us a bone since no free gold!
Finally how about a way to merge factions ... that way if I have a faction with 2 players and we have 3 upgrades we can merge our faction to another faction with 5 players. The new faction keeps all accumulated bonuses, money, concrete & then both old leaders are given joint control over the faction....
Just some thoughts!
