I really liked the game at first but unfortunately it is so unbalanced. Check your stats guys, see who people play the most. Mostly the first character you get. Playing him in 4-5 turns his attack can permanently become a one-hit-kill. No strategy needed than, pure luck. If so, than why not to give a permanent shield bonus to the Knight? Or sniper shot to the Gunner? Your league tables - look at top 100 - they all playing 1 OP character in 80% of their battles
