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
