Contest: Create a proliferated set!

So, instead of the Devs guessing and secretly and publically collecting data on sets that people would like to see proliferated, it would feel more involved in the community if they held a contest to let players design their preferred versions of power sets. The devs could give a guild-line and a bare-bones frame for power-set proliferation, what their formula is to create new primaries and secondaries from existing powers, what's kept, what's changed, and what's removed to create 'new' sets, and from there, the players go to town. They list out the powers they'd want for which AT in either primary or secondary in what order, and then it's just a matter of checking for valid entries, degrees of gimped versus overpowered, and then letting the community vote on their favorite entries that see developer approval

Yeah, it'd be a lot of sorting and reading work for whoever was in charge of the contest, but it would certainly let players feel like their helping shape the game just a little bit more themselves.

Minor quibble: 'Power Proliferation' as it has been used in the past is still for the most part just porting a set to a set-compatible AT (ie. ranged attacks between Blasters, Corruptors, Defenders) that doesn't have it available yet. Sometimes with little tweaks (such as all Stalker Melee sets getting an Assassin's ability), but generally it's just a port.

What you're looking at seems to be more in line with what happened when they built Elec Assault or Psi Manipulation, extending an existing theme to a set type not yet covered by creating a mix of existing and new powers. That's just that, a new powerset, IMO.

(But on that note, I still think Ice Armour for Brutes would totally work, unchanged from the Tank version except for numerical values.)
