I've respecced to a PvP MA/SR recently but it works just as well for PvE..
Here's what I did:
A bit of it hinges on what Travel power you take.I chose Fly despite being slow it generally allows you to reach flyers easily.
Pool Powers:
0. If you plan to take Fly then take also Air Superioty instead of Thunder Kick. Both do around the same damage but
Air Sup does knock down most of the time. Useful for slapping those pesky flyers to the ground.
1. I respecced Stamina + Fitness Pool to be taken fairly late on in my 40's. Mainly because when you go to Bloody Bay/ Sirens Call you get exemped down to 25/30.
Lack of stamina isnt a problem in PvP because often you can run away and recover. PvP battles can be over in a short period after all. Also by using one EndRed SO in most powers you can get by.
2. I took Stealth and Invis. For those with low 'perception' (ability to see hidden people) it allows me to be sneaky and get close.
If you take them before lvl 30 then they're usable in Sirens call.
Power Picks:
3. I took all the powers in MA (except Thunder Kick and Warriors Challenge).
3. I took all the SR powers except Lucky. End Rec
Dont forget the toggles increase your +perception.
Keep them on watch for when they get dropped - it's hard to notice sometimes.
4. Use "Cobra Strike" as your opening attack - it has a very high chance to Disorient if it hits. I four slotted it
adding one Disorient Duration.
5. I put 2 recharge Reducers on Practised Brawler. Meaning very little down time with Quickness. This is SR's only protection to being mezzed - but you will still need to carry a few Break frees just in case.
Finally stock up on Insights (yellow insps) and buy IR goggles. You never know when a stalker is about 
[edit] an alternative to Concealment pool would be
Leadership : Assault and Tactics - gives +Acc and +perception.
or
Medicine pool : for Aid Self.
From primary
Focus Chi, Storm Kick, Crippling Axe Kick, Crane Kick and Eagle Claw. Cobra strike is also good.
Secondary.
Focussed senses (+perception), praticed brawler, quickness and elude are the must takes. Rest are optional, you should prolly get them all, but you dont have to.
Strategy. Fight when elude is up, run when it isnt.

Well I was thinking to make my lv 30 MA/SR a PvP toon. Probably mostly for Siren's. I got absolutely no idea of which powers to pick (yeah I'm a noob in PvP :P) so I need help. All builds appreciated.
Thanks
