I think WP will have to increase fee to 3% eventually. Most of the Multipools go 3% or more today. As more ASICS on the network as more fees for low end pools. You can see that Mhash/hour was going down since the beginning of March. I hope it will balance and start going back up soon. But I think this may not happen because of the ASICS start entering the network. We may not know yet but KnC may already be mining with prototypes like they are known of doing - mining with customers ASICS and then when rate is down to crap they finally send those used miners with all kinds of excuses.
