I hope you put Tahm's shield at the end of the cast time, and buff him elsewhere if he needs compensation.

We'll wait for Worlds to go by and for the meta to settle after it to see where Tahm lands. If he needs a nerf (either because he's too strong or because we're looking to add power elsewhere), the E shield to end of cast time may be a good place. Would have to experiment with it.
