extremely important part of holding hate with pld
your autoattacks (and not just when youre in sword oath, its just as important in sheild oath)

gla/pld damage is absolute crap
autoattacks make up about 50% of his dps
so make sure that you are always facing your target
so if you just dodged something, as your coming back to your position, be absolutely certain that you face your target once more

also pld takes until level 50 to be any fun at all and to have a job quest that isnt super lame

another big thing is having a setup that youre comfortable with
for example this is what i came up with for war after about 2 days of playing on controller after switching over from keyboard
