So yesterday I was messing around in A5N (Fist of the Son) on Paladin because I got pretty bored of it and had another Paladin who wanted to main tank the boss. I'm used to MT, so I was like huh, I wonder if...
So I tried it.
Tank got Headache, boss rears back a fist, I popped Cover. Not only do I then take the damage I would have taken had I provoked, I ALSO got knocked back according to the direction the boss was facing.
Further, you can Cover + Sheltron and get a free Shield Swipe proc every time. The best part? Each tank buster is ~2 minutes after the previous one, meaning you can do this for every one of them, without ever having to use Provoke.
I would love to test this out in Savage and see if you can just Cover the MT to eat the damage (and obviously have the party stack on the MT if it's a stackbuster) without having to deal with Provokes.
This couples very well with A7N (Arm of the Son) where you can simply Cover the MT for Uplander Doom to eat the stacks (since the stacks don't apply to the tank if the tank takes 0 damage) and then it'll fall off and let the MT resume tanking without any janky swaps mid-cat nonsense.
I was the main tank in this (Tsukige Malqir) and he covered me for all of those except the one at ~6 minutes, where he provoked for the stacks and then let me take it back, since Cover wasn't back yet.
tfw Cover is finally useful for something other than saving a Warrior's ass after Akh Morn. ;-; Yay, Paladin!
