stopping interupts in pvp

I was hoping someone could help me out here, i run a mo/me and, since i am a caster, get interupted constantly in pvp. i was wondering on an an opinion to stop that? should i use spell breaker and lose my elite slot, Mantra of concentration or Mantra of Resolve? I am thinking mantra of concentration because there is no energy loss when it blocks an interupt, it last longer then resolve and it is half the cost. any suggestions would be appreciated!
thanks

Use the ring you found in the cracker jack box; that should stop them ;D

Glyph of Concentration would be the best bet... or learn to strife left and right to aviod arrows, cant while you cast.... you could always find ebtetr healing spells with lower cast times.

Mantra of Resolve + Spirit of Failure. Concentration would be another viable option but it only stops one interupt. Get a ranger running IA or Choking Gas and you won't be able to get a cast off at all. Mantra of Resolve will allow you to cast through the rangers interupts and Spirit of Failure should be enough to keep your energy up. I haven't tested it in PvP but I use Mantra of Resolve + Spirit of Failure + Throw Dirt for my ranger solo build and it keeps my energy up quite well. Though I'm sure stacking the 25% Failure is worth with the 90% Blind is worth helps significantly. If you do decide to test Resolve + SoF let me know how it works out.
