Hmm. That's some really big cap raises.
Basically tells me that the reason the original caps were there was so players wouldn't go into Update 2.0 with a bunch of classic and planetary commendations.
Nearly all MMORPGs do something to restrict the rate at which endgame gear can be accumulated.
The idea is that if it takes you a while to get all of your gear, you're going to be more willing to help other people get their gear. The problem with the method of caps is that it is counterproductive. Once you've hit the cap, you have no incentive to do any more group content for the rest of the week.
