Problem with rebels coming back means it would never end, and the bank would go on for hours.
Also a lot harder assaulting a compound than defending it.
Oh and all these people saying its 15 vs 50 you're wrong. Half the Police there have MK20's, with a few AR having phat guns so in my opinion...
OMG!!!!!!!! ALL of the people that 'hop on' do a combination of RP and combat like every single other person on the server. I have no idea where you're getting this thought from.
Edit: We all use 'illegal rifles' in the police anyway
