I personally enjoy vet the best, there is skill involved. Especially depending on what class you play, and competing against 29s aren't easy. It's a big challenge to fight 2 29s when your a vet in arena, or perhaps one bm 29 that can absorb 3k (lol). But I believe there is a larger gap between 29s and vets than you think. Enchants help a lot, but the gear and abilities they get are a HUGE advantage. Meaning that the skill lvl has to be there to compete against the larger hp numbers and damage of 29s. The issue with playing f2p is that they can't compete at all against 29s or certain vets. Only few classes like disc,feral,hunter, etc have a chance to compete against vets. So as great as a skill lvl a f2p player has, it won't have any room to show. It's sad cause I know they're a lot of talented F2P players out there, only to get one shotted by a certain proc. But like I said, depending on your class you can still be useful and successful in bgs and arena.
