well,i dont have the time to create/post a complete build, but i can tell ya what you prolly wanna go far as far as set bonuses.
There really is no need for perma-doms anymore, so slottn for +rech only isnt ness. if i were you i would slot for HPs/ACC/DMG. doms start off with rather low HPs, so gettn some bonuses and accolades to boost them up a bit is useful.
This is my first real PvP toon and I absolutely need help designing a build for it..but more importantly..the sets that I should use for it. I know purps are great but I'm sure slotting all purps isn't good overall.
My dom is GRAV/NRG and I heard only 4 powers are pretty useful in GRAV for doms so I can focus more on the secondary aspect.
If someone can take some time and post a build with ideal sets, I would greatly appreciate it. I'm freaking lost.
