Please, tell me your joking. Also, any dps class can hold aggro reliably if they try, this is why they have jolts and tanks do not.
If I wanted to maximize exp for any exp group I would do outside of like emberflow, I would most likely bot a paladin friend's toon.
Paladins. Stop. Whining.
hi I'm a monk, I don't even have a paladin alt/twink or anything. I'm simply relying on my experience boxing different tanks, and grouping with different ones.
As it stands, my monk does roughly 3-4 times more melee DPS than a similarly geared paladin using a onehander and shield. To make up for the aggro difference, paladins have several stuns (which generate much less aggro than they do on live) 2 different blinds which don't generate additional aggro until the effect from the previous application expires, and the bash bonus aggro. Last night the SK in my group tried out bash aggro, and with 4 tomes, better haste, and a shield with (I believe) almost 90 ac, could not hold aggro off a boxxed ranger with 0% haste items, under 100 AA, and t6 onehanders. Of course using bash alone shouldn't generate heaps of aggro since knights should still have to cast, but the SK and myself both came to the conclusion that for him, there was no noticeable aggro improvement over meleeing alone. He switched back to a twohander.
My point is this- With the way that blind works (not generating additional aggro until the effect wears off) paladins are hard-capped at a certain single target aggro generation. When they could actually deal meaningful melee DPS, this aggro amount was generally sufficient to maintain aggro. DPS classes still had to control aggro via feign/evade/jolt/concuss/etc, which is how it should be. Right now, the single target aggro generation of paladins is lower than previous, and in my opinion it is too low.
There are a few different ways to fix this. Allowing paladins to mitigate enough damage with a twohander to make tanking without a shield viable would bump their melee DPS up enough to generate sufficient single target aggro. Changing Flame of Light to do more damage, possibly with a debuff or something on it, would also help. Paladins are still (as far as I'm aware) supposed to be the highest DPS tank of the 3 tank classes, and right now they are the lowest. Either of these changes would help address this.
And as to my statement regarding other DPS classes being able to generate better single target aggro than paladins atm: My monk easily out-aggros any similarly geared/AAed paladin if I don't feign, so monks can definitely generate more single target aggro. Rangers and bards using things like atk debuffs, snares, slows, etc in addition to melee DPS that far exceeds paladin DPS, can likewise generate more single target aggro.
