In theory, E's passive is almost always better than its active after it's maxed.

Basically, E's active can at best result in Tahm receiving 50% damage reduction if he activates the shield exactly when he receives 50% of the damage that is suppose to hit him. For instance, say he is about to receive 1000 damage. If he activates the shield when 500 damage is already delt, his shield can absorb the other half, resulting in he recieve only 500 damage. If he activates the shield too early or late, say when he received 400 or 600, he will eventually receive 600 damage, which is a 40% damage reduction.

On the other hand, E's passive is a guaranteed overall percentage damage reduction if it's triggered. When E is maxed and not activated after receiving 1000 damage, he can recover 440 and only receive 560. This result is slightly worse than the aforementioned optimal case. Yet since it's almost impossible to use the active exactly when half of the total damage is dealt, I believe that passive is almost always better than active as long as it can be used.

In case of Tahm builds a Spirit Visage, the situation becomes even more one-sided. His E passive will recover 52.8% of received damage, which is ALWAYS better than using the active.

Therefore, I believe that in theory, after E is maxed and especially after he builds Spirit Visage, Tahm should always wait for the passive to trigger if the situation allows doing so and he should only use the shield when he's on the brink of dying and enemies are still dealing damage.

Ideas?
