Grav/kin here. personally speaking I felt this was an awesome combo. travel powers like the inertia reduction and siphen speed. and then the endurance siphen.. oh the fun with the buffs. As probably most of us here I have been around COH since the Start back in 2000's but. and the Nerfing that took place. the higher level Grav/kin is more attractive than the low level. (super squishy) The Pet singularity "B.o.b." is excellent companion. Spam holds...Annoying for anyone else lol. The one draw back I seen, is dimension shift (DS) and wormhole (WH) switched roles . WH use to be single target. and DS was AOE. now they switched them... its eh. DS was good crowd control.. Super hold that would not agro the other group. side mention though its cool to WH a group of low level baddies into the sky and watch them fall, in perez park. lol. I use to WH the Bomb in the Nuclear reactor mission, and drop it over the heads of the baddies, and then have the sniper take it out...good times. I will mention stay away from PVP... you can get owned lol
