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.
