Get TK, get ur cage, slot levitate for KU, slot up sonic siphon, get Dominate, get confuse, get hibernate, slot up for KB protection, and for your particular build ALWAYS team.
Ok, what about the rest of my powers?
And teaming wont help me in killing people by myself... >.< which is what I want (is to kill by myself), because I need the kill badges and stuff.
It's all about teams in PvP. Solo and you'll get butt hurt quickly unless you have good advantages. If I were you, since I've teamed with you before, I'd get every power from the Mind Control. Mass Confusion is up in the air for you to choose on your own. Since we can now have two builds, active builds 1 and 2, I'd save Mass Confusion for PvE only. TK is something you are going to have to try to keep on your opponent 24/7 as you are fighting and be able to manage your endurance while fighting because it will consistantly drain your end if you aren't careful. Just think of it as a hold that you won't have to recast as long as you stay close to your opponent, but not TOO close as to let them attack you. For teaming, you can lightly slot your defensive powers that effect teammates and not yourself and not have to worry about it. Actually, it isn't bad to skip some of them. Just think of how often you will be teaming with other people and which shields are most important for them. Then compare to what is most important to what YOU get out of the Sonic powerset.
tl;dr: Just focus more on the Mind/ set than /Sonic and you might figure out something sexy. 
Heh, That totally probably didn't help you much, but I saw your name and had to stop by to say hello. I used to have a Mind/Kin and it was totally different then how you have your character set up when we'd PvE in the past.
Oh, and ditch Whirlwind if you haven't already. lmao. It makes me laugh and unable to play.
Ok, I put those both together, and I should have enough info for my build.
(Hi Boxxy 
)
For my travel power(s), I'd like to keep super speed, but after the cheap "Foe Teleport" today, I'm not sure.
I think I'll still be able to keep both TP and SS, since I'll take out my stealth, and whirlwind, and have 2 extra powers to pick. I could get Foe TP, too, because if I totally take out SS, then what if someone uses foe tp when I'm teleporting... SL + SS might be nice, since SL I could get either another attack, or some defense, and for SS, I could get a faster recharge. Plus, SL and SS are the two fastest travel powers in the game.
Ideas/suggestions?
As far as sonic goes, I would suggest going into the Fighting pool for tough. On mids, an epic shield, pvp resist boost, dispersion field, and tough get you over 100% resist to everything, except for psy, which is sitting at 87%, but still over the 75% resist cap for Corrs.
Now, on my Dark/sonic corr Tough, dispersion field and the pvp bounus alone gets her 36% resist, and I didn't even slot for resist in neither tough nor dispersion field. (only had 3 slots, decided it was best to slot end redux.) Of course, Dark/ Has a nifty minor self heal, and since mind doesn't, you'd want aid self, so thats a travel power, fighting, fitness, and medicine. On my build I opted for tp instead of medicine because I couldn't fit in that second power b/c of Power Boost from Soul Mastery. However on a troller you'd probably have room.
As far as power selections go, I think everyone else has it covered...
...Just another way to think about building your character...
Well, as I said, I'd like to keep Super Speed... (Its one of my characters signature powers)
Anyway, I'll see how this all works out.
Btw, trollers still have masteries. I've gone with earth, since I hear it has good defense. So far it hasnt shown much support... but eh
And Earth's embrace is a good self heal, so if I just get the right enhancements for that, I can get a nice quick and effective heal.
Edit: Done. I've finished my respec, thanks for all the information I gathered. I went with TP, SS, almost all the Mind powers (everything but mass confusion), dispersion field, siphon, cage, fitness, fighting, and stone mastery. Thanks guys, hope this works (This was always my more fighty build anyway. XD)
u don't need AoEs for PvP.
Anyone know how a Mind/Sonic controller should have his build? I'm planning on doing a respec on my main character, and I figured I'd make it a PvP build. I know, "Mind/sonic is an odd combination!" I've been through that before. I'd really just like some help instead of a pointless conversation about how weird my powers are...
