Chasing flag carrier on foot - (example being shaman or druid in travel form or ghost wolf) they start to go out of range and you've used your stun :S You use Judgement..it procs and you catch up... Great! It doesnt proc = well meh, you mount up, go catch them.
Hunter disengages (disengage sends them 15yards back) you use judgement, bam.
Using it to move past people onto other opponents, very much like shadowstep speed boost.
I do know...50% only half chance to pop. Well for the amount of uses i can get out of the talent, i'm willing to deal with the fail rate.
BG's are mostly very situational, we all swap out gear, trinkets, use different consumables for different situations, this talent is of great benefit.
if your flayling around in midfield pounding person after person then i'm sure the 3% dmg would be wonderful but well, if your doing that...your doing it wrong i'm afraid.
For pve that talent is great but for pvp, it certaintly isnt game breaking by any means and that little bit of extra dmg i cant see making a determining effect on the outcome of the game.
All that being said, you stick to whatever you feel comfortable with. I feel better with my spec and find it benefits the way i play more....you prefer yours...whatever.... BUT by no means try to tell anyone that there is ONE spec because that dude is utter bollocks.
