Hunter Abilities

Specifically Hi-Explosive trap and Bursting shot in random battlegrounds. Is anyone else having a problem with these two spells performing terribly? They are kind of important and to have them work less than half the time makes a person think, "what's the point?"

Sure it could be lag, but everything else seems to work including dragons breath on my mage. Maybe these two spells need some tweaking to be more effective to compensate for lag? Am I the only one playing wow to have this issue?

I have even tried using slows before these spells and it helps in some circumstances but still pretty bad. It's like Gnome'ish engineering back in the day...
