(This is based directly on Chill’s original post, that was subsequently updated for the set bonus changes introduced in Game Update 2.0 and updated in Game Update 2.7.)
It seems every time I look for one of these online I end up with a dead link or a random reference that doesn’t help. So here they are.
In Game Update 3.0, we now have 2-piece, 4-piece and 6-piece bonuses. This means that there are now 7 item slots (head, chest, hands, waist, legs, feet, wrist) with gear that can have a set bonus.
Also in Game Update 3.0, the set bonuses for PvE and PvP were made the same. However, the sets do not mix and match; 3 pieces of PvE Vindicator and 1 of PvP Vindicator will not give the 4-piece bonus (instead, only the PvE 2-piece bonus will be active).
The 2-, 4- and 6-piece information below is from information found in-game, and is copyright BioWare.

For sorcs, the theorycrafters/guide writers are right. The old alacrity bonus is definitely better than the new set bonus. I got the new one anyway cos I wanted all the extra willpower and my DPS went down by 200.
