Im not sure if this is actually an exploit but im pretty sure blizzard doesnt want ppl to do it to much cause i got 100k hugs in like 5 mins and a gm warned me but i kept going so he dc'ed me and reset them so im guessing it kind of is but here it is
you just make a macro with like /hug and just keep copying it i personally think the /facepalm is the best tho but dont get to many to fast or u might get in trouble o.O
soz if its a repost or just not an exploit
wait before flaming my flame res gear is in bank
