Is it really, REALLY too difficult to wait a person to climb the chains and activate the boss earlier? Is it really too much to ask? We wiped almost every single time people didn't want to wait those 10 seconds. How hard it is to open YT and just watch a 2 minute clip that will save you sooooo much time and trouble? Unbealivable.
You know you can tell them that you are gonna be doing the boss cheese and not to activate the switch until it is done. Or post in your LFG description about it.
