Indeed, iff the R active effect hits an AP mage with 800 AP, it would deal 75% of it (at rank 4), making it 600 (1.1K with Lich Bane). But an average AP carry barely reaches 500~600 AP, so it would deal 375~450 magic damage to them. But about the cooldown you may be right. :P

Yeah, the W it's the one that I had the most trouble on making. But I'll redo that one too. :P

Thanks for your feedback. :)
