Pantheon needs a rework (Top Lane Solo Q analysis)

Brief Introduction/Context He's an extremely oppressive Top Lane Champion against Melee champions - even if they have a gap closer. And lets face it, it's pretty easy to counterpick someone in Solo Q where Role Priority is based off Pick Order (thanks for that by the way Riot).

Levels 1-5 Constant Spear harass. By the time you have the strength to retaliate, you're too low to stand a chance because his Passive will start proccing and he'll start getting guaranteed Critical Strikes. On the off chance that you have even health, you have to first Pop his Aegis Shield, get into Melee Range of him, survive all of his Point-and-Click damage that he does for the duration of his Point-and-Click stun, Pop his Aegis Shield again THEN you're on even footing with him.

Level 6 Level 6 Pantheon can then freely roam with Teleport and Ultimate with a cs lead he's probably happy to sacrifice a little bit, and 1-3 kills under his belt. You cannot counter his roam because you are still unable to go head-to-head with him, and (if he's used his Ultimate to roam) you'll end up sitting at mid/jungle while he's already TPed back to Top Lane and is continuing to build his lead.

Late Game Late game I'll admit that he falls off with a scaling pattern that resembles a cliff face - but that really doesn't help when you're still stuck at the bottom.

What would I change? Change his oppressive tools - point-and-click stun-gapcloser/100% Crit Chance vs. low HP targets/Aegis Shield. All of these abilities basically say "I can poke you for free and if you attempt to trade damage back, you're probably gonna die."
