how geared is your lock? because you should have no issued even if all you have is timeless stuff
the only thing to be aware of on kale is to not have your pet out. you cant get mind controlled if its only you there. but you can with a pet
you should be able to 1-2 shot all the advisors in phase one, AOEing the weps is a joke
3rd phase when they get rezzed is a little tricky but just pick up the staff so you cant get disoriented and you should be fine, take out whichever on charges you first. the rest of the fight is a cake
for ony I can kill her before she even takes off, so not sure why you are having an issue here. you can use your pet so it should be a joke (do it on 10 man) same mount drop chance, much less HP
only old legendary im missing is the main hand warglave on my DK, have HOR and TF and the Bow on a class that cant use it
haven't bothered with the cata ones yet as I cant solo them and I only do it when im bored. Have most of the drop mounts from old things as well
Couple of greens, crafted legs and a like 4 pieces of timeless stuff, the pet was the problem with kael, and i cant find the staff in time to avoid the stuns, Ony is a hit and miss, i dont have enough dps to kill her before she flies and i get overwhelmed by whelps, i do the same thing with the aoes but sometimes i win and sometimes i lose
