Damage should not scale off or Armor or MR

I was hoping it would be gone out of Galio's kit, and it ALMOST WAS, but he still has that damning quality that relegates a champion to niche play where they are either oppressive to a group of champions or simply lackluster against everyone. I'm talking about damage that scales with only one resistance. Rewarding a champion with a little bit of damage if they build HP does not have this problem. Every champion will build HP if they need to take hit. Champions like Rammus and Malphite though can have extremely erratic power based on the matchup. Malphite gets to build or gauntlet first? Great, he will do well in laning phase. Malphite has to start or ? He's probably having a lot of trouble in lane and won't be as useful as you'd like once he joins the team.

These "I counter X type of damage" mechanics aren't doing the champions or the game any favors.
