Only time I switch sides is when my squaddies go with or they are not on to fly with. Otherwise, I'm staying rook.
I was on this afternoon and the Rooks then too were being ganged and backed into corner in Orange at least, (did not make it to blue arena this afternoon)
As for the 2 sides and people switching to be on winning team, HT could just implement code so that if you switch sides, you dont get benifit of that side resetting a map until being on that side fr at least 24 hours. Maybe even charge perks to switch sides.
I'm just venting, I really dont expect a GD F'in thing to change, more likely get worse as has been the trend to date.
