Also, when you jump you glitch up a lot of effects like an opponent doing IWT/Charge/Intercept etc.

They seem to target the space the character was in, when the jump was initiated.
Much more often then not, the charge does not hit.

If you're using IS Boxer, create a mapped key.
Have it execute periodically, possibly once every 2 seconds or so.
Stick it into your default spammed DPS key.
Have it start deactivated by default.

Then create a two step toggle.
That enables and disables this mapped key.
Probably only for your non-casters.
As you wouldn't want to interrupt your healer toons.
