Rad/Fire/??? build

[BigDwarf99]

Hello all!

 

As the title states, I am looking for a rad/fire/??? build. My toon is lvl 47, and I will hit 50 sometime today. I have been using an old mids hero build for leveling. After searching the forums, I have found quite a few builds that are rad/fire/mu and rad/fire/pyre.

 

Which is better? Why?

 

If possible, some links to good mid lvl builds and high lvl builds would be appreciated. 

 

For reference, I played the game from the beginning, a little when CoV came out, and then real life happened, and I had to quit playing. A buddy showed me these forums and that the game was back, and once i hopped on, i was hooked again.

 

Thanks for any help!
