I didn't think they would sensor Get out the heck out [replace the heck with your favorite F-word]. According to the patch note it is an immobilize not a stun. The knockback had some situations that it was useful but it required delicate placement because the knockback itself was pure garbage. Smart melee know to stay in the middle of a ramp to avoid the knockback as much as possible from a talented Rocket Punch. Yes you might get an easy kill every now and then with a well timed knockback but you still get the AoE knockback. With the immobilze I can drop down and heal myself or get me that extra Tracer Missle + Railshot to kill them. With the Old Rocket Punch I would not be able to do that because they would have closed the distance in heartbeat.
You don't even seem like you play a Merc. I have a fully WH Merc that I have been playing since launch and this class is getting worse and worse with no sight of improvement.
If there resolve is full your Rocket Punch don't mean ****. Its pointless but they should of added it to the knock back.
