Is Flying Slam unreliable for anyone else?

[PatchKid]

Aside from the fact that it tends to put the target off in some weird spot, I can never get it to activate unless my target stands still for a second so I can get the damn ability to be "active".  It feels like all the other gap closing abilities are super reliable.  Destro's, BDs, Sins and BMs can easily get their gap closer mechanics off before I can land a flying slam.  Not to mention they call just grab us while we're in mid-air negating the ability completely.

 

Also, the window of opportunity is so small that it often wastes other abilities tied to TAB - like Fighting Spirit or Ice guard...

Yea, I wish they reduced the min distance and increased max distance, then it would be much better. I also find it weird that I get cooldown for slam shown on Tab when I'd rather use Ice Flower or Fighting Spirit. I have to turn 180 degrees just to activate them. Quite stupid design if you ask me.
