Out of curiosity cause I've been with some plds that couldn't hold hate. Overgearing is a problem, but for multipulls, how many flashes are you doing? And are you doing the multipull flash rotation? Most of the time, the pld runs in flashes once, and then starts comboing. Instead i've always done flash x3, then riot blade combo with a flash interwoven in.

I ask, because I don't have this problem and I notice you have reached 50 so overgearing should be even less of an issue with you.

Unless something changed very recently, I haven't had any issues tanking with pld/gld in low level content.
