PBE Changes for Gangplank Increase mana on Q with no mana return on unit kill?

On the PBE, GP's Q- Parrrley's cost was increased from 40 at all ranks to 60/55/50/45/40.

In the past, he used to have a mana return on unit kill because the spell had a higher mana cost, but now that the mana cost is larger, they didn't give him the mana return again? If you don't have the mana return, even killing MINION'S isn't worth it at all in early levels. With GP's base mana pool, 4 casts of his Q at lvl one makes him OOM. That's insane. This also isn't counting the other indirect nerfs he has received, such as losing the 20% potion and elixir duration without taking that new rune. Even if you are passive farming and NOT attacking the enemy, you're either stuck under tower getting harassed with no mana, OR you're stuck under tower, waiting for your laning opponent to stop freezing the lane.

I implore to give the mana return back on his Q, if this change goes through. What do you guys think of all this? I feel like this is more of a hard nerf rather than a light mana nerf.
