It is important to keep the users in the game as well since many old managers gave up because of the unbalanced engine.
Most veterans contemplate quitting because of 3 reasons:
1) lack of changes and new options. The game is ,and has been for a while, at a near standstill.
2) the ground game is too random and often the attacking skills not powerful enough.
3) the game owner is pretty much inactive on here and seem uninterested.
The game engine is pretty good actually, probably one of the best versions since I joined.
Reason number 3 is my main reason for being less active and having retired most of my fighters.
