Pay attention next time you fight a Reflect Damage Elite Pack;If you have LOH or LS with enough all resist, and armor, you should be able to handle Blue Groups or the Yellow Leaders with the Reflect Damage affix without having any damage reflected back. If you run into Minions with Reflect Damage, that's a different story. If you do more of a group attack and hit all of the minions at the same time, you will die very very quickly. There is a bug and it needs to be fixed.
Try it out and if you find the same to be true, bump the thread or request a sticky so Blizzard realizes there really is an issue and they need to revert it to how it was supposed to be. I really believe they did something during the hotfix on 10/23 to mess something up with Reflect Damage Minions. For it to be so specific, there has to be a problem. Seriously, Blue Reflect Damage Elties and the Yellow Leaders don't do a thing to me, but the Minions put on a world of hurt.
Also, yes, I can kill the minions, but it really is a nuisance to have to run around in the meantime waiting for my skills to cool down multiple times.
It seems that under certain conditions,(I don't know what they exactly are, but I'm meeting them) the RD Minons Reflect 2 attacks back and the Yellow Leaders only reflect 1 attack back. Give it a shot and try it out.
