Ways I though Grav/Time was better
Time gives
A second hold in Time Stop that I could stack with Gravity Distortion to Hold Bosses. Also Singularity Spams a hold as well. Holds are also excellent places to stack procs to increase potential damage
Unlike Speed Boost which does not work on me. Chrono Shift increases my recharge speed, increases my recovery, and heals. The increased recharge speeds means all my control powers come up quicker. And with enough recharge and slotting it can be made perma. And unlike Siphon Speed I dont need a target.
Slow Response is a solid debuff of -recharge and -res and when stacked with Time Crawl is even stronger
Farsight adds +Defense and + To Hit
And while you cannot heal a Singularity, Temporal Selection will boost its damage and it will boost its Regen rate and add 25% damage to Singy
Time worked better for me than Kin. I can buff my team AND myself. easier...
