I have a Plant/Psi Dom that is a Monster. I am at 205% Global Recharge and I have Perma-Drain Psyche which will keep your DOM motoring non-stop.
Also, nobody seems to mention how strong Carrion Creepers is once you can start stacking them. With 205% recharge, I can double stack Carrion Creepers for at least 30-40 seconds, which means you can easily control up to 2 mobs of 16 guys each (32 total guys). I have ran Rikti Warzone misssions and with Carrion Creepers, Confuse and the holds, I have controlled up to 48 guys (mobs at lvl 54) and lived.
In my opinion, you can farm faster than a Fire/Kin if you use the Confuse power. If you don't use confuse, a plant/psi might be a little slower farming but not by much.
