I7 powersets are announced

Here.
Includes the Thugs powerset for Masterminds (Pistols, Call Thugs, Dual Wield [pistols], Equip Thugs, Empty Clips, Call Enforcer, Gang War, Call Bruiser, Upgrade Equipment) …
… what the … Pistols? For a Mastermind? And not a Scrapper? WAUGH!
Electric Melee for Brutes (Charged Brawl, Havoc Punch, Jacobs Ladder, Build Up, Thunder Strike, Taunt, Chain Induction, Lightning Clap, Lightning Rod), along with Electric Armor (Charged Armor, Lightning Field, Conductive Shield, Static Shield, Grounded, Lightning Reflexes, Conserve Power, Power Sink, Power Surge). All sound fun.
Stalkers are getting Dark Melee and Dark Armor (flavored similarly to Scrappers).
Masterminds will also get to designate minions as a Bodyguards, which lets them take a third of the damage taken by the MM (who only takes two-thirds). Nice.
