Allies Must be Able to Block TROLL Tahm Kench from Swallowing Them

Tahm Kench must be changed immediately. All ally players should have the capability to block allied Tahm Kench from swallowing them. WHY? Today we had a ranked game in which a last-pick player stated he must be mid or he would feed. Someone else chose mid, so he took Tahm Kench (the only champion that can attack teammates). Before minions came out (while all are weak level 1), he swallowed one teammate and spit him out at an enemy turret. Then he followed our jungler, and swallowed him before he could last hit a monster (of course he provided no leash, so the jungler was weakened in the fight) and spit him out at enemies or at enemy turrets ... causing deaths and making jungler behind on levels. Currently, teammates can do nothing to prevent being swallowed. No other champion can hurt teammates like Tahm Kench. This needs to be changed immediately! Teammates must be able to block the ally swallow. The impact of troll Tahm Kench must be limited!
