Ya know, to each their own on opinions and all that, and at least some of you have acknowledged that the agro problem is sometimes with the other player not waiting just a second, but it's not true that only bad non-Jyre/non-Bango paladins are the only ones with agro managment problems.
I main a paladin and I don't box, and I can count on one hand the times I've afk'd for more than 5 minutes during ANY encounter, raid or otherwise. This means I am AT my keyboard, paying attention and active pretty much at all times. I go through mana like a crappy car goes through oil, and I still can't keep agro. Yeah, I'm not top 5 paladin, but you shouldn't have to be in order to be effective at your class.
In terms of spells only, when playing in non-undead areas I have our one little DD spell, a single target stun, single target blind, aoe stun, aoe blind. The aoes will agro the mobs that aren't being targetted, but they don't last long, nearly anything will trump them, and the cast time and refresh both stink. If (for example) some ranger gets a bow crit on an off mob and because he didn't assist it pulls to him BEFORE my aoe finishes casting, I'm pretty well screwed for ever getting agro. By the time the spell has finished casting, the mob is oor and I can't cast it again until it almost doesn't even matter anymore. Is this the other player's fault? Sure....but all the party sees is the paladin can't keep agro. IMO we NEED to be able to do this at least somewhat despite the fact other players might could do this thing or the other better. It gives us a role that helps the group without taking anything away from another class. I just can't see this as a bad idea. To give you an idea of how much better it is to have one or two other aoe options that add agro, in undead areas I have access to undead damage spells, and there I CAN forcibly maintain agro in a lot more instances.
