you haven't ran into snipes in multiples then. You are seriously pinned in your base for the whole game when there are 3+ snipes being thrown around. Any time you step outside, you get instagibbed, or at least your health gets low enough that you have to go back to heal. And then, by the time you come back, they recharged.
I actually do think it should have a higher recharge. It should be the sort of skill you use to get the last hit on a retreating DG (or, effectively lower the dg's health by 1000 since if he tries running below that, he's a dead man), not something you spam from halfway across the map without actually having to engage them.
Hell, it's not like regulas can't engage other demigods anyway. He's no slouch.
