I don't think we're at the right time for a vote on this yet. And I'm not really sure whether we're going about developing the FTL systems the right way either, we should maybe decide on a set of effects and limits to those effects, then figure out which cause works best.
Alternately, we could do it similarly to how we came up with races. Have a series of proposals, with causes, effects and limits put down already, then vote on those.
