How to bring Reksai into the Meta without making her OP

Passive: While Burrowed Reksai heals for 1% + 1% per 100 tAD Max HPs/s over 4 Seconds at the cost of 25% of her Rage/s

W: Knockup prioritizes Champions and is measured Edge to Edge

E: While Tunneling Reksai gains 10/20/30/40/50 Armor and MR and the Tunnel cant be interrupted (meaning if she Tunnels she will tunnel the same speed and distance even if rooted or slowed) but CC will take affect when she emerges from the tunnel.

R: Fix the Untargetable Bugs. She still can be targeted sometimes
