[Little Luan Ice/Cold Build]

Here is my ice/cold corr if you wanted a different perspective. I skipped snowstorm on it, having 3 rains already kind of pins you down enough. 

 

This is my favorite character. Both sets are just awesome.

[Katana Scrapper: What Secondary?]

My Katana is Kat/Rad and it’s one of my favorite melee characters. The added defense from divine avalanche really helps the resistance based set and Rad is just overall great. Would definitely recommend. 

[Looking for advice on tuning my Ice/Rad build]

I think your build is pretty decent. I made some changes that i think would make the character overall better. I didnt see a travel power, so i added one for kb points and ranged defense, Bitter Ice Blast animation is awfully long so I replaced that with choking cloud. I got ranged defense to 45% before incarnates. I'd recommend Agility for more recharge and end help. You could probably get rid of ice bolt and still have a good attack can with just 3 blasts, thats what I did on my ice/cold corr.

 

you could squeeze some more recharge out of the build using Superior Scouraging Blast as 3 piece = 10% rech however you will probably sacrifice ranged defense. I do usually try to split that set on 2 powers for the 20% rech.

 

As for Accuracy, I would think you should be good between radiation infection, tactics and a Kismet. 

 

I just updated my mids so idk whats going on with the resistance values here. looks to be messed up.

[What Dom is best for me?]

I’d recommend fire/psi or plant/psi for a starter dom. Fire plays melee and drain psyche is a great power which fixes end issues

[Looking for a magic water/dark corruptor build.]

Here is the Fire/dark build I am currently running. It's a great build, solos +4x8. The only thing to point out is when the next update comes live, Soul Drain is being replaced so I will have to rework the Epic portion of this build. Other than that, this may help you make your water/dark.

[I desire a little build help please. Fire/Ele/Power for 3 person team.]

Here is a build I threw together. Seems pretty decent. I think Fire/elec will be the perfect combo to support your trio. Both sets are top tier.

[Seismic/Earth blaster build help]

If it's me, I'm probably rolling something similar to this. I tried to keep as many of your power picks as I could.
