Yes, Issue 22 and Issue 22 Patch 1 updated the way Gravity Control powers work:
Dimension Shift is a 20-second, location-based toggle that immobilizes enemies, and phases both allies and enemies, in the area. All characters in the area are free to attack enemies (and are attackable by enemies). Characters can choose to stay safe outside the location, or to move between phases. The toggle can be prematurely turned off to remove the phase effect early. Recharge time reduced from 90 seconds to 60 seconds.
Lift (Controllers only) increased in damage.
Propel casts faster, the projectile travels faster, and does "splash knockdown" on up to three more enemies near the target.
Wormhole's radius increased and will no longer cause aggro on the caster.
Singularity's cast times reduced for Crush and Gravity Distortion, and Lift increased in damage.
Impact! introduced: Enemies attacked with Lift or Propel will have bonus damage applied if the enemy has been recently held by Gravity Distortion (regardless of who cast Gravity Distortion).
