Druid 4 piece resto bonus is of questionable use in certain types of fights, especially 10 man versions. Plus the set visually looks rather... monstrous. Druidy, yes, but in a corrupted like Felwood sorta way. Maybe that is warranted, coming from Icecrown Citadel, but I think I'd only be purely ok with it if it was from some corrupted Emerald Dream instance or something. :p
Also disappointed with Blizzard's plans to have haste affect hots. A buff in certain ways, yes, but enough of a drawback in other ways that I probably won't be pleased if Blizzard and others try to call it a buff.

On jousting! Note that the basic attack Thrust is not tied to the same cooldown as your other 3 abilities. I've done more jousting dailies than I care to admit and have found it works best to use a Thrust after every use of any of the other abilities. It ends up feeling a bit bouncy -- Shield Breaker -> into melee range for Thrust -> back out for another Shield Breaker -> back into melee range for Thrust, etc. Thrust as you Charge into them! Thrust as you refresh your shield.
I am staving off inappropriate jokes now.
And most classes/specs can solo Chillmaw, the only hard tourney daily. Ret Paladin is one. I don't know exactly what sort of gear level you'd need to do it, though. My
Enh Shaman manages well with fairly poor gear (worse than his armory shows, even, especially in the weapon category). My hunter manages with worse gear, but only just barely, and I'm pretty sure there's no way he'd manage if he wasn't BM. I'd expect a Ret Pally to manage about equally well as Enh Shaman at the same gear level, as they're very similar, but I can't really say firsthand. As Nephyr said though, it's pretty darn easy to get a group for it (which will often then go on to do a moderately difficult jousting daily at the citadel to speed that up), so if you want to avoid any potentially fatal testing, it's easy enough to manage that way.
