Thanks to Runycat, I found out that Polearms are now trainable by druids. Makes sense, right? Hunters get to use feral staves (and they're converting strength to AP on them to make them more desirable), so druids now can use those hunter polearms. And we can all covet each other's neighbors, or something.
Trainers are in Stormwind and Undercity, in case you've forgotten.
So let's go to the comparisons! For bears, there's still no replacing Origin of Nightmares, Staff of the Plague Beast or even Enraged Feral Staff - they're just too good with the armor, even post 3.0.8. That one's pretty easy. They also have more stamina than any other druid weapons out there. It's not a contest.
For cats, though...
Black Ice (which drops from Malygos Normal) becomes the second best DPS weapon in the game. The huge hit rating is great and rare on any druid weapon, it has a ton of agility and a decent amount of attack power. It also looks like a druid weapon already; it's all crazy looking and funky and stuff. I really recommend this if no one else wants it; the hit rating will make it alone very valuable, and it has the highest agility of any weapon out there.
The Wraith Spear drops from normal Naxx from Maexxna, and it'll be worse than a lot of the other options for DPS. All of the feral staves, Inevitable Defeat...but it's not a bad one, and it should make for a nice alternate weapon if you can't get anything better.
Cryptfiend's Bite drops from Heroic Heigan, but it's not ideal. It has crit and haste instead of hit and haste, and only has 51 agility. Nice AP on it, but I'm not convinced that it's enough.
For those of you on a budget, the Saliva-Corroded Pike (yum!) drops from one of the random bosses in heroic VH, and will be close to the quality of a Feral Enraged staff for dps. And for an even bigger budget item, you can get the Whale-Stick Harpoon from Kalu'ak, which should be a very good early DPS option since you can get the rep so soon.
So - if you happen to be on any Malygos normal runs and that Black Ice drops - and no one else wants it - make sure to ask nicely. :)
And you don't even have to level your polearm skills either.
