It becomes a problem if the group doesn’t want to wait around for you to piddle around with no threat because you’re leveling a weapon skill. Not sure how else to explain it.
If the group doesn’t care, then no, its not a problem.
You guys seem to forget its implied that the guy was running a dungeon, with other people.
EDIT: You can level a weapon skill up from 0/300 to 290/300 in two pulls? Thats interesting.
EDIT 2: You guys are also forgetting that the OP is stating the weaponskill threshold in question was 45/300. If its out of 300 its indicating that the tank is level 60, and thus presumably running a level 60 dungeon.
This isn’t Wailing Caverns or something where the cap is what, 0/100 for players that are level appropriate running through?
