What if Tahm Kench's swallowed target can still be damaged when you attack Kench?
If Tahm Kench swallows an ally/ enemy, enemies attacking him will hurt the person swallowed for X%. (This means they can hurt their own allies. )
As it currently stands, Tahm Kench is trash in SoloQ because of pro-play. His get-out-of-jail-free card E works like a low CD Kalista ult, how about making it a Mikael's crucible instead? And then maybe he can be buffed elsewhere.
