I've heard that DOW 2 is on the horizon, it's just that the horizon will probably wind up being a couple of years away. :pull:
Here's a thought; to reproduce the effects of synapse AND simplify Tyranid resource gathering, Tyranids could gather requisition by plopping down a synapse creature on a critical location (and when a Tyranid creature incorporates a requistion point, it loses its mobility). Yeah, I know it's not 100% accurate, but DOW isn't for folks that demand complete accuracy. Also, Tyranids could be allowed a certain number of Ripper swarms that generate resources as they fight.
