1) Lower class ground units become useless far too quickly which results in them dying very fast. This causes players to constantly use up money to replenish them.
2) Why can units level up well beyond 100 but not gain additional abilities? Their stats are laughable too. Seems like this is just an excuse to make players shell out money for in-game currency or grind like mad.
3) You pretty much have to hardcore grind for war funds or buy some with real money.
