There is a hunter pet bug from EPL that has been around for a while from my understanding that increases the pets damage by large amounts, more than intended. I do not know the exact details of it, but others have been talking about it.
I noticed a Council Heroic 25m kill log that consisted of a 2 minute fight. The hunter was BM and using this pet. I also noticed other guilds doing it. I am not trying to rat anyone out so I am not mentioning any guild tags here. I just want to know that if you use this pet bug to get one of these heroic kills in ToT, is that against TOU since the bug has been there a while and blizzard does not seem to be concerned with it as there has been no reaction from the developers themselves. This pet was used on a Tortos kill as well. So, if the developers do not seem concerned with it, is this just one of those "it is okay to do it even if it is wrong" kinda deals? I do know one of these guilds would have not met the dps requirement for heroic council if they did not have this bug in the raid.
