My bad, my maths was wrong. You only need to spend 5 seconds to recharge all of your runic energy, seeing as 20*5 is 100 and 20*10 isn't. As for the slowing the whole team down, that's a good point, maybe I should change it so that abilities can only use up 50 runic energy, so that you can at least use 2 before reconstruct is necessary.
