Mana cost I'm assuming is just to normalize it since he's an older champion. But it's worth noting that it had 80 instead of 100 because his W requires such a high amount of mana and needs to be used fairly often in order to win the lane as Talon. It is my belief that his ultimate's mana cost wasn't standard because of this, in order to keep him a viable champion.
Also, that's a rather drastic cooldown increase. Since the nerfs he received a couple years ago to his base values and scaling values, his ultimate hasn't been a hard hitting spell in the first half of the game. What's the context behind reducing its availability?
Thanks for reading.
