Its my turn to say the bugs.
Ill start with death knight (since this has the only bugs i found yet)
Some of the quests as you explained dont work, especially Grand theft palomino and others. Will be fixed by ArcEmu. Now the huge prob: whenever i create a dk, i get a random Season 5 gear, i had rogue and priest s5 gear and some cool wotlk weps. Well if u want a blizz like repack what the hell is that o.O Ok i solved the problem by executing a new table for that.
I noticed that Death;s Grip works. Awesome. Ill update when i can.
