The jump itself is instantaneous, yes. However, I think there should be some base Power cost per second for having a Motivator attached to your Ship. Otherwise you could just stick a Motivator and a Computer on a bare Ship's Core and instantly teleport yourself around the whole solar-system using the Power stored in the Beacons.Wait, energy usage per second? Isn't the jump instantaneous??
I only included a cool-down because everyone on here seems to think FTL will be a horribly un-balanced get out of jail free card if it doesn't have one. I agree with you there should be no artificial cool-down and just have the more natural one of waiting for your Power Tanks to re-charge. This would remove the need for the Expander altogether.Shouldn't there be no intrinsic cooldown, only something regulated by the power demands required?
I don't see the need for a separate FTL-only Power Tank. FTL travel itself simply uses your existing stored Power at or below a linear amount by default. Much more intuitive and no need for a new block type.Instead, the expander creates a pool of FTL-only energy that gets charged after the main ship power is full. The expander energy pool expands at or below a linear amount with the block count, unlike the existing power tanks, which expand above a linear amount. It would be used on small ships to increase FTL range.
