level 54 charm spots (necro)

[Reguiy]

Starting to level my necro a bit. I did 37ish-54 in CoM charming and it was glorious. I gave up leveling on him for a while and now I've been trying different spots with little success.

I did HS and at 54 it seems too low. Was getting a ton of charm breaks and resists. Same thing goes for KC and CoM 2nd top floor. I tried the skeletons in the NE corner of DL and they were basically all light blue. Then I tried the BW giant fort, and after charming for so long I can't go back to fear kiting as it's just too slow.

So anyone have some a good advice to get me through 54 and maybe even 55?
