I have only played for 2 days and reached lv31 (at position 87). So far this game seems to be awesome and pretty balanced.

some suggestions:

1) 1st mover advantage too strong. Here're some solutions I can think of :
-penalty on 1st mover (ex. -1 action point)
-bonus for 2nd mover (ex. extra attributes)

2) "Potions" too expensive. For my current level range I have to consume 1-2 "potions" per battle to stand a chance to win (since others use them too). It becomes very hard to save enough money for upgrading when leveling up. (it's designed this way so that ppl wanna spend real money I guess)
