You may want to respec at 32 if you want repulsion field.
I've found that once Force Bubble is available you really don't need repel.
Also i found that Mass hypnosis as standard was up for pretty much ever mob already without recharge unless your team were in total carnage mode, in which case you didn't need it anyway, but also Force Bubble really takes it's toll endurance wise, if you can spare them and extra end redux or two wouldn't hurt
Otherwise slotted pretty much the same as mine 
The pellet with the poisons in the Vessel with the Pessel, the Chalice from the Palace has the brew that is true...
