After using the new Rek'Sai ult you feel a bit lost especially when the enemy juns turns 90° and runs away. I think it would be way better if she'd jump out of the underground to slice the enemy and then jumps right back into the ground. This would give you a good opportunity to follow up with a knock up onto ur target. Right now to me it feels like when you use burrowed Q + 1500 range ult noone can follow you at all because it takes way too long to use W for a knock up. You just get a cc and all enemies are gone.
