I agree with BGB.
You need to fight back - it's actually easy to get coins atm, the problem is that humans can't sit in front of the game 24/7
there is room for improvement, and these improvements are ongoing.
players need access to semi-afk play.. basic bots
I think that when everyone has auto destruct + gather, it will level the field some more.
Anything that makes a playing session less time consuming would be a good thing.
Perhaps a "Word of Recall" type item that can be found randomly like hearts and activated like destruct?
Specifically for the casual player. If it comes with a cost (or a risk to lose all coins)
than the guys who dominate the center won't use it, and the game mechanics are not dumbed down too much.
If it later turns out that unsupervised generals get killed most of the time when they walk through the chokepoints
to the inner ring... well, then we also need a dangerous to use random group teleport item.
