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.
Naw...best way us still one stasis hunter and two curiass titans. Freeze, thundercrash and dead before he makes it to his ramp. Trick is not to do too much damage so he doesn't run before the elevator stops.
