Swain nerf should be reverted

I think the nerf to his W is a little extreme. First of all the ability has an insane amount of cooldown ( 18 seconds at level 1) and it is the last ability to be upgraded, meaning it's at this cooldown the majority of the game. Swain can't effectively get a kill UNLESS he hits a champ with this, allowing you to take full advantage of the extra damage benefits of his E.

Further more, W is not an ability you can spam away, because of it's cooldown, and also because of it's high mana cost. Also, it's not like it's a point and click stun, it's actually quite hard to hit properly if your opponent is expecting it. If they fear it so much, just rush some boots and you are good, especially merc tread boots. Swain does have counterplay to this ability, but he however absolutely needs the stun to solidify a kill in lane. When I played him today and actually hit a W, it was over so fast I was un-sure to if I actually got him with it. I barely had enough time to even walk up to them to do anything.

I hope Riot understands that this nerf was too much and does something about it.
