Best remark yet. Definitely archiving this one.
But all silliness aside....
I play a healing Merc. I play almost exclusively PvE content, hence the PvE healing spec (so no Rocket Punch knockback for me) Not that I'd get to use it that often. I've dabbled in PvP, but not too much.
Since we can use all our abilities in PvP, I agree we have a lot of CC's in WZ. But for someone that doesn't PvP, I get very little use for Rocket Punch, Jet Boost or Shoulder Slam. (Only times I use Jet Boost is to knock mobs down that hole so you get to the bosses faster). And to be honest, even if you could use Jet Boost or Rocket Punch (with the talented knockback) to interrupt movable mobs, you really don't want to spread them out, or move them away! from the tank. That's just silly nonsense. That leaves Electro Dart and Concussion Missile, which I love and use all the time.
In FP's and Ops I tend to stay in the back and I have seldom problems with agro. So no real reason to run in to melee range anyway. Now IF I had an interrupt (a proper one, that works on knockback/stun-immune targets) I'd consider running in. But as it stand now, there is no reason to.
I'd be open for a Melee interrupt (ex. Shoulder Slam, as mentioned earlier). Or Jet Boost because you already interrupt players because of the knockback, so adding the interrupt to bosses as well shouldn't make a too big of an impact. Except that it is aoe then ofc. So perhaps too OP. But then we have Rocket Punch. At least for us healing Mercs it's single target. and on a reasonable interrupt cd, 9s. Could even change it to 10-15s and I'd still be happy. Some Mercs have the talented knockback, which already interrupts. So again, adding the actual interrupt parameter should impact things too much.
But then I'd rather have a ranged interrupt, But I'd take the melee one if it were between melee and a none.
Even if I can't have the car that runs on farts, I still want A car!
My 2c anyway
