Thanks everyone for the help. Good to know that Hide really is the alpha and the omega of stealth, and I needn't bother with other kinds.
Android - I should have specified that this character is soloing only at this point. (He's a Praetorian on Defiant, not much other option

.) I realize that strike and fade is not the optimum playstyle for a stalker, but A) at level 13 I seem to get annihilated whenever I'm fighting more than 2 opponents for more than 5 seconds, B) I kinda like the "strike and disappear" thing for style purposes, and was just wondering if it was at all possible, and C) as long as I'm the only one affected by my sacrificing efficacy to feel like a ninja, I don't feel bad about it.
Again, I appreciate the pointers from everyone.
