Tahmn literally defines the term "Unkillable champ" in top lane
Top lane full tank Tahm is literally an unkillable champ. The moment he puts a single point into his E it takes a full 5 man gank to even come close to taking this guys down. on top of that his Ult's passive's damage gives him an unrealistic amount of harass and and damage to back up his dominance in the top lane.
I really think Riot should look into toning down the protective power of his E skill.
so get good mate.
