Well, the problem is not really JackieChan or even the GK clan, but the autobalance that does not care classes.
It's annoying to see all archers/HA go in same team, same for cavalry.
The infantry can do nothing against runners.
For me an Ha = 2 or even 3 archers.
and a gen10 level 25 is more dangerous than a gen1 level 30.
Autobalance for me, or rather incompetence at balancing is killing this mod.
That's why people prefer saturate the already full 120 players servers than joining servers at 10, 15 players.
