I mean, good for you? I always give tips to new players when I end up in a low level dungeons and I see them struggling or explain the mechanics if someone is asking for it, but if you think I'm a tryhard elitist harda** on sprouts because I argue for people to play their class decently well? go off, I guess?
If you think that me wanting someone who has spent several tens (hundreds?) of hours playing to play their class in higher level dungeons/trials/raids well: what exactly is wrong with that? they've invested a lot of time into the game already and should've have a rudimentary grasp on the underlying mechanics at least, so wanting them to actually put their knowledge to proper use is wrong?
lanada said it well: it could serve as a wake up call to players who think they're doing well - to make them actually do well; it could serve as a reality check for toxic players who think they're god's greatest gift to earth when they were in fact doing less damage than both healers who's giving everyone crap
but I digress: I'm probably one of the nicest players you'd meet in game

, I just want people to
try to be as good as they can!
