@ImoutoMasterI was refering to the fact the character with that name (they could have re-rolled) is a hongmoon 17 character. Iirc if you do the current storyline + the orange / blue quests to get the rest of the starter gear you finish at hm16. (There is call to arms gear on the character so it's not fully storyline geared, however based on the fact it is hongmoon 17 tells you that the character hasn't played much at all.)
Also a bug is something that isn't doing what it is supposed to, so if you want to make the arguement of it should reset on the ledge (even though it is within the range they wanted the boss to stay in combat so technically not a bug) then that would also mean that anything the devs ever change because they decide it is not the way they intended / want it is a bug. This would mean that "skill change" patches are simply a giant "bug fix" because they don't want them to work that way. That would mean there is no such thing is a buff or nerf, those are also simply "bug fixes". No class is ever over or under powered, it is simply "bugged" because "not as intended".
