For the last you mean bleeding wound proc, I doubt it will be anything to worry about based on our research but it’s certainly a good idea to blacklist it right away.
The DT hex bug is a bit hard to police but we could have a rule where DTs are forced to rezone on death (prepare your cursebreakers!) although the bug does not happen in that many encounters. For sure it’s nothing to worry about for a quick, timed run!
The only class stacking I care about is necros + poms to abuse HC or necros + tos to get crazy damage with the pets+blue heal. I don’t see an issue with stacking anything else if people want to. I think having multiple conqs or multiple barbs is cool for example, can have them using totally different spec and buffs etc.
The tos bugged feat will be controversial because a lot of people use that as their main spec but I 100% agree. Tos does not need it at all to do great damage or be a great asset to the team. And it’s a very easy one to abuse on purpose or not.
