The tractor beam is super bugged right now. I would say this is the biggest reason why it was pulled from season 3 launch, The graphical issues could be dealt with during a hot fix but the tractor beam is a "I win" button.
In case anyone hasn't tested the tractor beam, it awards +9 per second to all systems when in use. The devs only want it to grant a flat +9 (at least i assume so)
I went and took a look at the sets on Tribble tonight. Aegis is very Tron-like, but I like Aegis' look more than the Borg set. I expect it to be nerfed before it goes live, though. On my fleet escort, the ECM Array put my defense at 104%, which is great for survivability, but I suspect it's a bit much in terms of balance.
I've heard reports of 115% with the Assimilated set. I have no worries as it they all will be better balanced before released to Holodeck. Though for the trouble to get a whole set it may be alright as is.
