Some minor tweaks for Hecarim?

Any chance for us to get a slight mana cost reduction on Hecarim Q for him to find his way back into the meta?

(E.g. in gold he's at #88, in Platin hat #97, in Diamond at #101 and at Master he's at #123 out of #135 champions in terms of winrate, I think a tiny buff wouldn't hurt https://euw.op.gg/statistics/champion/ (Date 7th august '17) )
