I am always open to changing my opinion based on experiences of playingI never disliked the game at all, I just found it a tad unbalanced mainly due to the unlocking which favours people who play it more and unbalances the game too much imo and the maps(i still don't like a few of them, but some have grown on me)
It can still get very frustrating though, the unlocks are ridiculous and i do think they are generally a really bad thing in shooters but if you work through it you can start to hold your own against the massively overpowered unlocks. I still rage when i see people with much more powerful weapons/unlocks. And there is no point even trying to fly as i don't have any unlocks for it!
Playing with more teamwork and slightly adapting my playstyle has helped me to enjoy the game a lot more.
It has also helped that i tweaked it a bit to get much better FPS as well, I was happy with around 30but now i have tweaked it a bit to get around 50-60 most of the time
Also 32-player servers are MUCH better than 64!
Yeah, I totally agree about the unlocks but it seems to be the way of things these days.

The upcoming DLC will probably make it even worse if they start selling people overpowered weapons as well.
