Might work for a specialty server as t00l says for the Ladder league types. I might give it a try once, but I suspect I'd lose interest pretty quick and find myself playing City of Heroes again. I could be surprised, but I wasn't very interested in any ladder leaugue pay, and although I enjoyed filling in as a replacement from time to time, such stringent structures just don't hold my interest. Still, I'd be willing to try it once, if I could manage to stick it out on GW5 I figure I'm willing to tolerate anything once.
In all honesty however, for my personal preferences this is a step in the wrong direction. I think its ok to reward certain ship choices but I'm very much against restricting of others except at the furthest end of the spectrum.
