I kind of hope by Cataclysm, they sort out Paladin to make it a little more fun to level; although, to be honest, based on endgame numbers, there's no fucking shortage of people getting Paladin to 80. It's ridiculous.
Kind of continuing what I was saying on the last page (got a little buried at the end of the page so I'm kind of reiterating a bit), here's some things I noticed about leveling a Paladin that could use overhauls/tweaks in Cata:
1: Crusader Strike should be baseline. It's so boring as a talent, but you're mostly standing around auto-attacking while waiting for Judgment to come off CD without it.
A baseline version would be fine in a form weaker than how it is now, i.e. with a 6-8 sec. cooldown rather than 4.
2: Retribution should be able to spec into "Imp. Crusader Strike" which would add a Scourge Strike 3.3-like secondary Holy component to the strike. I'm not really sure on what you'd base such a bonus damage component off though. Perhaps just a static amount which would automatically get increased by Vengeance stacks?
3: Basically, you have no attacks at low levels, but you also have no mana. This is one of those things that gets "fixed" once you pick up Judgments of the Wise, and/or other talents from the other trees, but it's pretty shitty for the first 45 levels when you don't have access to that ability.
4: My guess is that CAN'T do it without redesigning the game since you can't have more than one stance bar, but it seems like the design of seals should be something akin to stances, rather than buffs that actually fall off when you die in a BG or something.
I guess in the end I just hate the way that many classes feel so horribly incomplete and/or gimped while leveling, and suddenly become Godly right around the same time: Level 45-50 when you put enough talent points into a certain tree to get some ability that should really be baseline.
