Funkilla

I am currently lvl 50 and have mu mastery. I enjoy playing my toon but I'm just unfamiliar on what route to slot the IO's. I was hoping someone might be able to suggest a build for me as I have a ton of respecs saved up over the years.

I just came back to the game after quite a while and I have been trying to decide which of my toons to slot out. I have a robot/FF MM and I was curious if it would be worth slotting it out or if I am better off just making a new toon. Thanks for you input and any suggestions on a build would also be helpful since I am essentially loss when it comes to slotting.

I just came back to the game after 1367 days and I'm completely lost to say the least. Would anyone mind helping me with a build that I can aim for for a fire/therm corr. Thanks for the help.
