Making Rudra's more powerful isn't going to make THF more useful for hate management than other jobs, or make it wanted for anything other than TH.

So basically, the only situation that Rudra's is currently good (Party/Ally play - hate control, TH stacking) is taken care of, and now Rudra's will become a great WS to use unstacked in solo play as well for a job than can already solo nearly everything.
