like the OP said if we force leap than we get knocked back and it's a 15 sec cooldown. if we save it for the knockback we eat a bunch of lightning and are 50% hp when we get there.
stuns we have are hilt strike (1 second), force stasis (channeled unless you spec it in the defense tree. three second stun), and force leap does a very short stun if you spec it.
hilt strike - cooldown 1 m
force stasis - cooldown 1m
force leap - cooldown 15 s
we have one slow that you have to be in melee range to use so it's useless against a sorcerer. They also have ranged slow, roots, stuns, etc etc. way more than us
