Tahm will never be balanced if his W remains the way it is right now
As it stands, his W occupies such a colossal part of his total power level that everything else in his kit will always have to be weak in order to prevent him from being hilariously overpowered. The main reason is the fact that W's cooldown is incredibly low from rank one.
Increase his W cooldown to something like 26/22/20/18/16 or 22/19/16/13/10 if we want to preserve it's final rank cooldown. An ability that's as strong as his W shouldn't have a 14 second cooldown at rank one.
