Been playing a bit. It really is a great game, but there are a few problems. Partially due to the small team size, the winner is more often than not decided by not having that guy who's never used a keyboard before and ends up going 1-8 with 2000 damage. I've played about 40 games, and I'd guess only 5 of those had a team where everybody was at a basic competence level and someone wasn't less than useless. It reminds me of MOBAs in that respect, since it is very common to have one player throw the game, but the matches are quick enough that it's not nearly as agonizing.
People also disconnect constantly, and the matchmaking is somewhat notorious for taking way longer than it should to find a match. I think they may have gotten some of the kinks out recently, though. It seems fairly balanced, but I'd say Team Edward is way better at a low skill level than the Hoomans, while the Hoomans are better at a higher skill level when the stars align and everybody plays well.
The economy is interesting, way more so than I believed at first glance. At first I thought it was going to be a slog to get all the necessary items without spending money, just judging from gold/match and the costs for permanent unlocks, but there's actually an additional random element. Leveling up classes provides free stuff periodically, and others drop randomly like in TF2's system. At first I was planning on maximizing gold spending by never renting stuff, but it turns out that you could very well spend 1500 gold on something that you'll just get another (sometimes better) copy of later. It makes me think renting is actually better than buying anything permanently, except for stuff that doesn't drop.
All random dropped weapons seem to have some minor stat differences, with some having a "charge" bar (not sure how that works yet), while others are leveled up by earning experience with it equipped. So if you do play this, I wouldn't recommend spending gold on permanent unlocks that can be obtained through drops, since sooner or later, you'll get a random one for free. So far all the classes I've tried can be played competively either stock or with one item change (Alchemist, Prophet, Hunter, Reaver, Tyrant, Sentinel), so items aren't even strictly necessary to be credit to team.
