Warp shadow says +6000 stealth after 14.5 seconds for me anyway. I'm kind of curious but I have a feeling some of these abilities are not working as intended, however I have no idea what these abilities were meant to do exactly.
As for plasma shockwave thing, use it when an opponents shields are down and then say it's useless. Can be quite devastating if timed right, however it's rare you'll have an opportunity to use it.
No clue what you are talking about in regards to the shockwave. I only fire it off when surrounded and I have managed to bring the enemies shields down. It is also quite handy when taking on the little buzzing fighters. But it is a situational ability, not something you would fire off the second you are able to.

Not sure what your doing or its bug on your end however I used Warp Shadow last night in PvP with others in our fleet and it worked great in conjunction with combat cloak, was perfect for getting out of combat and repositioning urself.
Plasma Shockwave could use a small boost but even that was good, you need to dump points in particle generator so that could be were you get a good amount of dps from after you put some skill points into that.
Shield Heal was great! Ive been testing with a tactical so it was nice to have that extra heal ability.
