I beg to differ. Stability is king in PvP, and this was amazing for rezzing and finishing and everything under the sun. Unlike PvE, you don't really stay in any kit all too long anyway, you just pop whatever skill you need from it and exit back out. It's what I do, anyway. Therefore the 50% slower movement speed didn't really matter all that much, not compared to getting free stability whenever you wanted.
Run up to the downed guy, enter FT, Stomp like a boss.
Run up to a friendly, enter FT, Blast them all away, Rez like a champ.
See a 100B Warrior while out of Stamina, enter FT, eat the Bull's Charge, blast him away as he wonders why you aren't ass-first on the ground.
Now you get some Might, if you stay in the kit long enough. Massive nerf. For PvE Dungeons and sPvP.
