There are 2 HUGE problems with mods 2.0.
1. You can only equip 6 star mods on g12 characters, so if you don't have a bunch of g12 toons don't bother. You'll only screw yourself out of a useful mod. BTW, I don't remember that part being mentioned in any of the posts we were showed.
2. The cost of moving mods is atrociously high. 6 star mods cost 8,000 a piece. That's 240,000 a team, if you have to move mods to do an event or raid. For mid range players trying to do Heroic Sith who don't have enough good mods to go around it will add up fast. CG needs to either give us more credits or lower the price for mod removal.
