Warning for "Grief" Tactics?!

[TaleraRistain]

You try healing a player who stands in aoes one after the other, runs mechanics into other players, runs a stack marker alone to the edge of the arena, gets pushed into spikes, stands next to a tank with a tankbuster, backflips off the side, gets pushed off the side, stands in an instakill mechanic (LoTA, Amon, etc.), etc. Yes, it is their fault.

I've healed all of that and more and I really don't see the big struggle in having to do our role when our party is less than perfect. Does it matter that it's their fault? Not to me. Maybe you just don't have the mentality for being a healer in groups with random matching where unexpected things can occur.
