If this is a bit out of topic let me know. I think that paladin could have some simple buffs to help it out and not make it OP or anything. One of the main problems is the lack of DPS this could be fixed or at least balanced more by doing something like fixing sword oath which in my opinion is garbage. Sword gives you an amazing 50 extra potency to auto attacks why can't this be changed to something better like 10% dmg increase with the 5% accuracy increase from shield oath or 10% dmg increase overall or 10%% dmg increase and and the auto attack potency. Even just a 5% increase would be nice to have something other than the dinky 50 potency maybe even a bit higher. One of the things that has bothered me for a long time was that if a warrior kept maim up with their tanking stance their dmg reduction is only 5% right? Paladin seems a bit forced to rely on Fight or Flight for dmg increase while tanking or dps'ing granted its 30% dmg increase but overall its not gonna be much.
There is also the fact that it seems it any of the other tanks want to especially warrior they can just rip aggro through tanking or pure aggression. They could also give paladin a natural dmg buff that isnt oath based like a 10% innate dmg buff buffing their global dmg up by that 10%. The dps increase would help generate aggro on either stance and up dps in turn making them more useful overall. The class is kind of reliant on its cooldowns but with proper manangement i've never found it an issue. As for abilities not stances/oaths that could be changed I believe the PVP skill glory slash would be great in PvE just without the knock back having 200 potency and being an aoe frontal cone aggro generating move. Other than flash we don't have much in terms of aoe aggro generation however that makes sense seeing as paladin is more of a single target tank. However it couldn't hurt to give one aoe ability. Rage of halone could be altered to be a smaller cone aoe at least it would be something. Circle of scorn could also generate a bit more aggro or deal more dmg per tick since its potency is 30 why not make it 50? Not a game breaking buff I would think. We could also buff shield oath to be more useful and have a larger aggro generation maybe or dmg reduction or both.
