2 ways works and I suggest being on voice chat,
1way, is to have everyone on turrets and turn them into the middle and kill behide your teams mates.
2 ways i healer of turrets and the other 3 killing, both ways works, done many times, fun place to do, can be annoying when you wipe alot and have no idea, I suggest to not do with a PUG...
So basically, we have a level 40 normal instance which requires precise timing and voice chat, when most hard modes don't. Does this seem right? I am calling this a balance issue. Like I said, it needs to be toned down.
