Here in the States there is a huge push back to pump guns even at the pro level. The LA Iron Men play pump a great deal even against the semis. Semis are being capped at 10.5 BPS these days so the ropes of paint are a thing of the past.
If airsoft is more tactical and more objective based then a good sniper team should be very effective. It sounds to me like airsoft is very much like the PB I played 15-20 years ago. I believe that is part of the appeal for me. Airsoft is what PB once was. PB is heading back that way, very quickly actually but the realism of Airsoft weapon systems is very appealing.
