I've been having a lot of fun since the start of this expansion on my level 80 twink. I'd like to bring to light something that affects this bracket, and whilst I know that it's not 90 so not many people actually care, I think it's worth hearing about. Feel free to make any comments you like, but be aware I'm not proud of what I've achieved, as I just want the bug removed.
Since MoP brought with it some awesome gear (and changes) for my class, I've been having a lot of fun soloing old raids, and have discovered a rather unique bug, as shown in this video:
A brief explanation of the bug:
Through paladin mastery scaling at this level, it's actually possible for me to get to over 100% damage reduction when I use Shield of the Righteous. The vengeance formula uses % damage reductions to reverse-engineer original damage taken, and provides a broken figure due to dividing by zero.
I've already reported what I assumed (at least, what I found a few weeks ago) on the official forums [EU] here: http://eu.battle.net/wow/en/forum/topic/5560866231. I don't have access to the american forums, but I have reported and ticketed it ingame.
Here is a list of other "important" bosses that I can solo but level 90s cannot:
