Eh. There's this fine line between being new and being clueless.No, yeah, that was a jerk move to be sure but this guy seems just as bad tbh with his "I shouldn't have to" crap.
You really shouldn't have to look anything up for any non-raid-level encounters. Spoiling yourself the encounter just to save a couple of minutes for some guy?
I think the responsibility is on experienced players here. We have to realize we might get paired up with players that aren't on our level yet and it's okay because that's how the game works.
