So I like the Hecarim buff... but

I'm not sure this was the right thing for him. I never had an issue with surviving in a team-fight so long as everybody was right there with me inside my Spirit of Dread. If you're going to give Hecarim a buff, do so by reducing the cost of his Q at later ranks. Q is something you're supposed to spam in a team-fight and 40+mana per Q can deplete him very quickly.

Anyway, I could be wrong here, but this buff just doesn't feel... meaningful on him.
