You don't understand it, I, a Sniper, will root the Sentinel so that he cannot jump at you and kill you. See? Now take the legshot away from me, and i will not be able to save your butt.
don't you have an automatic root on your punt, independent of legshot? or maybe every sniper/gs I encounter has the two abils macro'd (possible).
honestly, though, how long does full resolve (i.e., whitebar) last? 4s? 5s? how long does a root last? 2s. there is not "resolve" system for roots, so they can be daisy chained ad infinitum. half of the whitebar is lost in one root, and anyone else can reroot whenever. meanwhile, the whitebar continues to tick away.
why would anyone ever be upset about that?
the system is bad. but I've already said as much. so flame on.
I think what you are referring to is the interrupt that accompanies the leap. If we lost it as a baseline feature, I think I would be ok with that.
But leap most certainly does NOT apply a break-on-damage stun to the target. Some Jugg's will use their AoE mez after they leap into a pack to position for the Smash, but that isn't part of the leap.
i'm pretty sure I had to spec into that on my watchman.
for the other guy...
a mezz after a leap?
the guardian tanks have something more frustrating where they gain cc immunity after their leap.
the root after leap is specific to combat spec and goes along with master strike. it's core to that spec, and there are a lot of ways to circumvent it anyway.
