Ok so here is what I ended up with after a couple of hours on mids. A few notes on my thought process...
- Yes I know how expensive this build is, especially the couple of PVP IO's that I threw in there.
- I ended up taking only a few of my ice powers. I found that when I am playing Ice Slick gets nulled out by teammates so I dropped that. The other ice powers I almost never had time to use so I figured what was the point of keeping them around.
- Not very familiar with Power Boost but I was recommended to take it by a friend so I worked it in.
- I was really having issues finding a place to stick all of the slots so I ended up 5 slotting brawl to hold Hecatomb.
Any advice will be appreciated, thanks for reading

The biggest problem here is your lack of accuracy in key powers. Fulcrum Shift, Siphon Power, Transfusion, and Transference must hit in order for you and your teammates to benefit. Tactics and global accuracy bonuses help, but if you intend to participate in any of the task forces before level 45 you're going to need to slot accuracy.
Also, reconsider Ice Slick. When you are the sole controller on a team, it's effects will be tremendous. Communicate with your team when there are other controllers. There are times when Ice Slick will be needed more than AoE immobilizes. Warwolves, for example, will shrug off most immobilizes but will bounce around on an Ice Slick.
Increase Density is also a power I feel people throw to the chopping block far too often. Learn to use it selectively and proactively and you can avoid many defeats and unnecessary healing. Remember that it offers knockback protection, which I find more useful than the fear or confuse protection found in Clear Mind. The only thing it's truly lacking is protection from sleep.
Finally, rethink chasing resistance and regeneration. With a much smaller pool of hit points than the AT's your accustomed to, you'll find that they have a much smaller impact for a controller.
So I played around a bit and came up with this taking in what you said above. I am going to wait until I hit 50 in a few days and play with all of the powers to decide what to do with the Ice Slick and Increase Density, but the point is definitely being taken into consideration for sure.
I really don't know much about Increase Density and while it looked amazing I have never been buffed with it in this game by another Kin so figured nobody ever took it.
I moved Power Boost to my last power so that I could six slot gaussian's and slotted my main Kinetics powers with accuracy IO's as you said for the lower level tf's.
Appreciate the help, thanks

I have never really ventured from the Tanks/Scrapper/Brute build and know very little about archetypes outside of this bubble. I currently have a Ice/Kin controller at level 38 and am working up to 50 pretty quick. I would love any advice as to where I should take this toon once reaching 50. A few things about what I am looking for:
- I have a great farming toon so this won't really be needed for that.
- I will most likely use this toon primarily for TF hopping so am looking to build it for team use.
- I am not worried about spending inf, so if purpling up in the best way to go I can work with it.
I would like to try and work Veng in if possible but only if it doesn't take away from everything else too bad.
I will try and get something up here for you guys to go off of, but I am pretty clueless.
