Not because a skill is there means you should use it. Of course it could make the instance of that particular moment be a saved one, but hey, mistakes happens, PS4 controller don't have enough buttons etc..
Somes are playing this game for what is should be:
Fun.
Some takes a game too seriously.
For us, it's quite simple:
1- is this a Raid? Yes -> Be serious and put out all that you can, and get ready to listen and adapt.
No -> enjoy the game the way you want it, as long as you clear what you got yourself into. Even if it takes 10-15 more minutes than what Some would like.
