stacking

Mob Stacking system: It's fun to have 200 skeleton spawners, but if they die 1 by 1 (due to the stacking system), it's the same as having 5 spawners. I've read that there's an option (within the plugin) to kill an entire stack of mobs on death. Ofcourse this would lead to bigger lag issues...

Alright, So i want to address the servers Mob stacking, the server is one of the best survival servers and i want to be able to have a working farm/grinder without mob stacking for the simple fact it makes using the spawners much harder also theirs is a ton of glitches with it i killed x3 sheep...
