Rakan E Costs Double the listed mana
According to the Tool Tip for Rakan's E (Battle Dance), the mana cost should be "60/70/80/90/100". However, I noticed that when I cast my E, the mana consumed is actually DOUBLE the aforementioned mana costs. I only noticed this after the recent patch. Also, this has nothing to do with the re-casting of the skill. This happens after the first cast.
