The grand company argument hasn't really meant anything since they added freelancer, though. The people who lose over and over will blame all kinds of things - and for sure, building a partial premade might help - but one of the things I never see in complaints about win rates is an analysis of why an individual might be part of the problem themselves instead of an elite PVPer perpetually hamstrung by a failing grand company (most of which will be made up of freelancers anyway).
Personally, I'm ok with them keeping exp as-is so long as they add some kind of incentive for winning beyond 'slightly faster gil from desynthesis', which is about as unexciting as it comes, and the mounts/gear everyone already earned months/years ago at this point.
