Suggestion for Rek'sai's Tunnels & Ult

1 of the biggest problems with Rek'sai is her ult. It doesn't do enough for the high cooldown it has. It's so reliant on her tunnels that sometimes you don't even have a chance to get a good ult.

So a suggestion. If you step on a tunnel it only destroys that part of it, it'll also grant vision of the second part of the tunnel. Rek'sai can then come back to the side still there and rebuild the tunnel when you go through it. The enemy does not get vision of the part rebuilt. Remaking a tunnel puts E on a 50% cooldown.

If you ult to a tunnel that has 1 part to it you can choose to go to the side which is already up or burrow your way through that section to rebuild it fully. (You'll have a highlighted part of where the other side of the tunnel is)

Note: if you choose to burrow to remake a tunnel the speed going through that tunnel is the same as when you're actually making them. Also if you ult to the part which is already up there's a 10 cooldown so you can't immediately remake the tunnel. You have to choose between 1 side or the other.
