It's not that i like Archpriest but there is nothing I despise more than these malicious fucks who try to ruin for people just for the sake of causing something bad to them. In my eyes even a pickpocket who steals 45e from someone is better as a human because the thief's motivation is just getting money not causing something maleficent.
Pallys are fine. You just have to play with the right classes and adapt.
The strongest setup as holy i can think of is feral hunter pala but even in that you can just replace the pala with a priest and you get a much much better comp. Do you think ele lock pala is good? Just replace the pala with a restodruid and you have a stronger comp. The same goes for any setup. I bet you can't name a single comp where a holypaladin is clearly stronger than a different healer would be.
