Death Knights – Don’t expect much Death Knights. Blizzard has been back pedaling on this class since it was launched, trying to find the right balance and their next expansion is the perfect chance. Whatever they get will be undoubtedly cool to watch, but probably not that useful.

Druids – Druids have always been the beneficiaries of some mighty nice talents. However, there is little buzz coming out these days about what could be the next big attack for these guys. I imagine the Feral Druids among you will probably benefit from some increased Druidic powers in tanking, but that’s a mighty thin guess.

Hunters – Damage, damage, damage. Don’t expect anything less. Whether it’s a new pet class or a series of new talent points to help avoid damage, Hunters are all about the DPS. Expect bigger and badder Mark talents and some really cool pet effects.

Mages – Time Stop – a really good Time Stop too. We don’t know anything for sure, but Cataclysm is sure to bring some big fireworks to the Mage. They are getting up there in power and we’ve seen some pretty spectacular spells being cast by raid bosses.

Paladin – Restoration is probably set, but Protection and Retribution are going to get some major boosts to PvE effectiveness. For the most constantly changed class in the game, expect another series of buffs that are too heavy and then get scaled back for a while after 4.0 is released.

Priest – I’d imagine we see some more debuffs and buffs in the upper end for the Priests out there. Healing spells are good right now and can be scaled up for levels, but the buffs and debuffs are what really add value to this class and I think we’ll see that in Cataclysm.

Rogue – Rogues, much like our Hunter friends are all about DPS and will see the same kinds of insane boosts in their DPS in Cataclysm that we’ve come to expect. Don’t be surprised though if we finally see a couple of nerfs to this class, making them less “all powerful” in PvP. It’s been a long time since they’ve been at the top of the PvP charts and Blizzard has been thinking about retooling for a good long time.

Shamans – Who knows. Shamans have undergone a lot of changes since 3.0 was released (almost all of it good), but it’s impossible to know for sure when those changes will stop). I’d look for something non-totem related though. The totems are becoming ever more powerful but are largely support.

Warlock – Time to fix the Warlocks. All you locks are probably rubbing your hands in anticipation of Cataclysm because this class needs some love. Hard to tell what they’ll do, but a major retooling is likely.

Warriors – Don’t fix what’s not broken. Warriors have been the most stable class for 5 years now and will likely remain that way with minimal changes and few buffs. More damage absorption and a higher AoE threat generation are likely, but nothing else too spectacular.

Cataclysm is a long ways off, so it’s impossible to know what changes are coming, but when they do start coming, you can bet that there will be a lot of discussions and arguments over just how useful the new class setups are. It’ll be an interesting winter.
