"in AC the planner uses the EFPS to coordinate in and out aircraft, TC coordinators don't have the time to do that."
Do you mean that TC co-ordinators don't have time to co-ordinate (ie everything is on Standing agreements) or that they don't have time to co-ordinate electronically?
Electronic co-ordination, for routine traffic, is far faster than the mediator system for the offering sector and gives the accepting sector the choice of prioritising the traffic as he/she accepts it.
