Feral druid leveling / dungeons Im currently leveling a feral druid in TBC, im 57 with mostly questing and a few dungeon drops. I know the gear will be replaced quickly and i plan on questing in Hellfire before trying to run any dungeons. 

My questions are

Is feral leveling basically mangle to max CP and FB? on the off chance im dpsing in a dungeon is that really the best rotation?

Also i like to tank, but ever since the prepatch ive noticed my threat gen is horrible, i know single target is keep mangle on CD and swipe is now the best filler? even for single target? AoE threat is always an issue so im worried about tanking while leveling  

Any input from experienced druids would be appreciated
