I posted it and then edited it because I wasn't on the latest build, but sure enough every build seems to not take Accurate To Hit Debuff sets on Glittering Column.
Dominators: Glittering Column takes To Hit Debuff sets and also takes Accuracy enhancements... but doesn't allow Accurate To Hit Debuff enhancements, which seems wrong
I just did a respec to this build, I am 46 at the moment. I think your build thoughts were pretty solid and I will go this route. I think I might see about stuffing Combat Jumping in with Super Jump but the rest seems ok.
Yeah Kinetic Melee and Poison are probably my top two set adjustment requests. Then third to do whatever is needed to fix Super Strength so it can be proliferated to Scrapper/Stalker (which I assume means playing with Rage.)
Another thing that could help is not having the Interface ability that adds immob to critters be so weak and infrequent compared to other Interface abilities (except the confuse one, which is also made weak.)
I'm only up to 39 at the moment but I forgot how annoying it is to be a MM without Electric Affinity's kb protection. Pets go flying all over the place all the time if you are going with resists over def.
