Correct me if I'm wrong, but that looks like LK 25 H due to remaining hp/%. Either way grats on that ! I'm in the process of gearing a 80 DK twink, unsure if they're capable of soloing LK 25 H. Paladins seem possible now due to the change on grand crusader? DKs can probably pull out surviving the fight, I imagine the problem will be the dps still.
On another topic, I'm not quite sure what seems the other best profession perk here second to Blacksmithing (sockets). I considered engineering but really wanted to get secondary stats as bonus, or am I underestimating Strength/Stam too much? I thought Alchemy for the stone, mastery + str seems fairly awesome.
I see that you've started to update your list of kills and you forgot about my paladin so I'll just share my actual list of kills:
2x Paladin bugged kills (from before last update)

Strange i thought that they fixed that AP rocketing in 5.2. Have you tried it? Anyway i am not doing it anymore and i am not planing to do so, as you can see on my armory atm . Are you sure you checked good armory btw. There is my old character still on Aerie Peak after i transfered it to Outland about 4 weeks ago
