LIGHT in TFT

I found Rito to be quite biased towards the LIGHT. It is too powerful for hyper roll users.Healed for 25% of the champion's Maximum Health,it's too much.I was played Sivir with RED BUFF,it's still restores 200-300 health per champion and with 1-2 Redemption,they are immortal.Each match sees 4-5 players play LIGHT OMG :(( so boring.They are losing the diversity of the game :((.What should I do now? and how to counter LIGHT. thanks every one
