Is it PvE based or PvP?
CoH PvP SG = SuperUnion - Co-Leader - Union/Freedom
CoV PvP VG = Disruption - Co-Leader - Union/Freedom
Global = @Rent & @Rent.
Playgroup are all **** - Global Handle
I made this build for PVE, I have no idea how to make effective PVP builds but I'm guessing powers like combat jumping, stealth etc would give the extra egde. Will most likely use my second build for PVP should I feel I want/need to do so.

Ok, that's no problem. I only needed to know so i can advise accordingly.
[Edit] After having a good look at your build i'd say you've slotted and enhanced quite well. There's things i'd change personally like tough and weave but you may have a concept going which incorporates those 2 powers.
Nothing else i can say to improve on really

looks good build played a claw/regen stalker for over 2 years fun alt to play, just one thing the pet from the epic powers not best to use as it gives away hide in PvE unless they changed that and i missed it 
Kittens ftw
Only useful as a distraction. however because you're likely to be hidden, the pet would take agro first.
Heh I've been using the "Loa Bone" for the temporary zombie like that.
Currently working on getting all Villain AT's to 50 and for stalkers I am going Claws/Regen. Wondering if this mids build seems ok and if someone with more stalker experience can give me some pointers.
The level slotting is a bit off its just the way I added the slots in mids.
