A Posable Solution To The Problems With Rek'Sai's Ult / Discussion

So, a complaint I've seen all around the internet, stated during the cast of LCS, and one I've experienced myself; Is the extreme ease of dodging Rek'Sai's ult. Many people have been calling for a reversion of her ult to her pre-rework state, but i for one love the direction Riot took it in the rework, so i'd much rather tweak the ability than see it totally removed. My idea is to put the ultimate on a vector, allowing the player to select the direction in 360 degrees around the target for Rek'Sai to emerge, strike, and fly through the target. Not only would this solve the problem of 100% predictability of her ultimate, I also think it fits her fantasy MUCH better, showing she can move freely underground, not just in one straight line, like her tunnels and current ultimate. Leave your ideas on how to improve/fix Rek'Sai's ultimate below!
