I always think that Aid Self is a must for a /SR for PvP and PvE. You'll already have a 'Panic Button' with Elude so consider dropping Invis and Phase Shift for Aid Self (and one other from that pool)? Also suggest 2x End Reductions for your toggles.
cheers smyte, aid selfs kinda the one kinda having to think about hard, reason for the invis/phase is to hit -percept cap cause of the amount of ++precept floating round RV, plus the phase comboed with temp power phase 1 min of phase to get away heal etc. so can see why debate about hasten/ss invis/phase aid other(or stim)/aid self
No Divine Avalanche? It will make you hit s/l/melee def cap 
compliments /nin very well but not sure if it's necessary with /SR.
Not sure you really need stealth, invis and phase. Only one type of stealth can stack with hide at once. If anything in that set I would take grant invis and team up with another stalker that has it in pvp The most +per you can get after you is a scrapper with tactics, FA and a per toggle, which not many do because it'll crush their endurance.
This is a build i've kinda got in mind, any comments or suggestions folks?
