Tahm Kench is harmful to the team

I have just spent 3 games in a row with a giant frog that was trying on purpose to help the other team. As the adc, I do the most damage in a fight. Every fight Tahm eats me. This misses me 3-4 auto attacks, and even kills as Tahm walks away from the fleeing enemies. This is far worse than Kalista, whom I already hate, because the range you lose from him eating you is far more than the range you can shoot yourself. It is also on a far shorter cooldown.

TAHM KENCH SUCKS ASS.

Solution?

1. Make it so you can eject yourself immediately.
2. Add a toggle button that disallows being eaten.
3. Add more range so you can make up the lost ground from the troll Kench
4. Remove this unpolished and poorly thought out champion.

(He has no harass and no initiate. wtf is the point? He is a 2ndary initiator I guess?)

Please Rito... every new champion you release has more and more own team troll potential. Do you know how many ace in the hole's I have missed because of Tahm eating? I shouldn't have to dodge every Ranked game I have a Tahm on my team.

Edit: People seem to be missing the point. Yes other champs can mess with their own team, but Tahm takes far less skill to do it, and is a far less cooldown.
