What ive observed since 2.1 when warriors got buffed till now is that the real problem with pld is the skill that actually makes their dps competitive. Sword Oath.
Its just way too big difference between the oaths.
Just making Sword Oath into a trait or removing it and balancing the other skill potencies would pretty much close the gap there is while MT.
Cause thats where the problem lies.

I don't really agree making SwO into an even more desirable stance to prioritize.
