Pantheon should really have the Q cooldown refund removed

He's stomping both top lane and mid lane because he doesn't really have any weakness.

The W -> Q -> E combo is obnoxious and offers very little counterplay, and what little counterplay it does offer is covered by the refunded Q cooldown.

If you're a burst champion, it's impossible to win trades against this. If you follow and wait for his invulnerability to drop, his Q will be off cooldown shortly after and you'll be too close to avoid it. If you're not a tank, this will easily take 50-60% of your health.

If you rely on sustained damage, you just straight up lose because his cooldowns and mana costs are so low. He basically does sustained burst damage if he can use the refund.

If you try to avoid interacting with him because you can't win trades, he's free to just whiff spears at you and zone you off the wave. He's basically a caster with a top lane fighter's kit. The only things that can actually lane against him successfully are tanks.

I don't really understand why this mechanic is necessary.
