The only job left with a remotely effective means of non-damage hate generation post-RDM nerf is BLU, with Fantod generating 320 CE and 320 VE on a ~5 second timer with gear/buffs. Even in my best enmity gear, that's not going to maintain hate over any DD just because of how the game works. Also, it's not like we even use disengaged tanks at this point in the game anyway.
Hmmm, maybe make fantod lvl 49 or less, then paladin cap "cap" defense without reducing attack (hate) and get a nice hate tool to boot.
