Can zed W come off cooldown and be used again before the shadow despawns?
Rank 5 living shadow has 14 sec cooldown, (reduced to 8.4 with 40% cdr, 7.7 with 45%). The shadow lasts 4 seconds. Zed's W, shadow slash reduces Living shadow's cooldown by 1 second per enemy champion hit (only for Zed's slash, not his shadows).
Now imagine Zed uses his W, then Es all 5 opponents (cuz they really want to give him a hug).
Living shadow's cooldown is reduced to 3.4 (or 2.7) and his shadow still has ~3.5 seconds left. What happens when W comes off CD and the shadow is still alive?
Could Zed make a second W shadow by swapping and then hitting W again? It seems weird that this scenario is possible outside of URF.
