So until now it was a good time to pug HC dungeons.
Players pugging dungeons were quite good, all the groups I got into were from good guilds in the server. This is because doing HC require revered and players already attuned were the ones putting in the effort and the time so they were skilled and knowledgeable.
However, right now the average andy has hit revered and is doing hc dungeons in questing gear without a clue of what he is doing.
Best avoid pugging HC dungeons for a couple of weeks till average andys get some badge gear and kara gear and they start outgearing the dungeons
A couple of hints to see if you are in an andy group:
1- The group composition is messed up, like having 1 fury warrior and 1 retry paladin in the group, or 2 shadowpriests, or a retry paladin in general.
2- Members of the group don't eat food between pulls and expect the healer to top them off instead of eating.
Feel free to add more hints.
