I have 40 hours in this now and am still enjoying it, it's good to jump in solo for 30 minutes to an hour, the competitive play is good as 5v5 actually makes deaths and re spawn timers mean something.
It has it's problems and imbalances still but it's beta after all.
Had some good games with EWJ, Trell, Mr Q and Unspecified last night and it was great fun if not bloody intense on occasions.
Bushwhacker is my go to Merc, managed a 47 for 3 on him a few days a go
who needs grenades and air strikes when you can run and gun and catch people out with a sentry.
