I'm just starting to get into seriously gearing Paladin and I was wondering if the +1 Souveran armor set was the way to go? Or a mix of that and af gear?
It's not the absolute best in every slot.... but it's basically the best in every slot.
Special notes on the head and the legs:
Head: BiS. Period. Sure you can get DT and enmity and whatnot from other pieces... but it's the only iLv piece with "reverse Store TP" on it. And on WHM (and on PLD too), I've seen the massive difference that one piece has when in PUGs with PLDs using it and not. It seriously cuts enemy move use by a substantial amount.
Legs: There's so many options here... But if you don't have a Burtgang,
you better be using them empy pants. Burtgang lets you forego the empy pants as you'll have that effect already in it... but that extra retention of enmity can be the key difference in you being able to keep hate off of your DDs.
Or at least that's what I've seen in others and experienced in myself.
But there's a bunch of legs options. If you can make Sulevia work, their TA+4% can be good for your DPS... such as it is. And it doesn't depreciate your AM3 if you're using Burtgang. But Souveran+1's enmity and everything else makes it near-BiS if not outright so. (It all really depends on all your other gear.)
And even if there is something else better than a Souveran+1 piece, as hard pressed as I am to think of what that is, each piece offers you some other utility to it so that having it is still worth the investment.
