yield

I would like to request that some rules became more specified. As pickups are allowed... they are allowed when? Before round only or all the time? (even during a round... yes, it means to get bit away from combat area). About the bases... when defending all players must be reachable by foot? Or not? I request this not for my personnal or my team use, but because there are some smart guys that take advantage of not well specified rules. Thanks.
