Seeing this a lot too. I'm playing different combinations of sets I liked before. 
  
My Live main stable of regularly-played level 50 characters: 
Elec/nrg/ele blaster (first hero) 
Elec/elec/elec dom (My praetorian) 
Fire/fire/fire dom (enjoyed this before and after dom improvements) 
Elec/elec/mu brute (my villain) 
fire/kin/fire controller (Farmer blue side) 
dark/fire/mu brute (Farmer red side) 
shield/SS/earth tank (Team-oriented tank) 
elec/kin/elec corruptor (team-oriented support) 
Emp/elec/leadership defender (all-in Empathy with some ability to sap endurance) 
  
My Homecoming stable of characters: 
SS/Elec/Mu Brute (main and somewhat of my farmer) 
Elec/Kin/Medicine pool Corruptor (teamplayer) 
Dual Pistols/Ninjitsu blaster (seriously, been waiting for this combo forever, Shadowrun theme) 
Elec/Time/Primal Controller (kinda glad it's easy to level stuff, this is strong but slower than I like to play) 
  
In progress characters on HC: savage/bio, Fire/TA blaster, remade all-fire dom which I'm wavering on with all the proliferated sets. 
  
I mean come on... they have Traps on controllers lol. I'm debating Plant/Traps or Dark/Traps (huntsman-like with the big dog) 
  
  
I think we're all making things using past experiences and trying to make new experiences using them. Eventually we'll settle into some new stuff with maybe a remade original when it's all said and done.
