I’m crap at multitasking and my brain decidedly experiences doing a fight and processing said fight as two very different tasksSo if there are a lot of mechanics, phases, different mechanics during different phases… I’ll be dead a lot if I don’t process it beforehand. In that sense it’s more pleasant for myself if I look it up before I go in, I skip the whole: what the bloody hell do I do now/what does this mean/run away or stack waaah/panic! phase. And it’s a matter of respect for others to not force a dead idiot of a healer on them.
It’s different when it’s new for everyone, and to be fair, usually after two or three tries under those circumstances I get the fight. But then it feels a great deal less like unnecessary pestering of innocent strangers!
