I had a dream about a sequel to League

It was actually REALLY cool.

The map had multiple tiers, and every champion had the ability to jump to (or otherwise reach) elevated rocks or cliffs on the map.

You could switch between first person view and top down view, and your champion has different skills depending on which perspective you're using. When I was in first person view and playing Ezreal, I could use an ability that slammed his gauntleted palm into the ground, which created a spell-nullifying zone in the area that you're looking at. Also in first person, his E allows you to Arcane Shift onto the side of a wall, staying there for a moment before he automatically slides down.

There was also a champion that was strictly first-person view and played similar to Unreal Tournament, where he can double jump and wall-jump, and can switch between weapons that he can pick up throughout the map (but if an enemy picks the weapons up, the weapon gets an increased respawn timer)

In the store, Riot was selling "Classic skin packs" that made champions look like their League 1 versions. There was also a Dragonblade Garen skin that I remember seeing.

Talon in League 2 had two skins, one of them looked very Assassin's Creed-ish, the other one was Dragonblade. In first-person view, Talon moved slower and had no HUD, but he was able to climb any terrain, getting up to the highest parts of a map if he was given enough time. His passive gives his first attack more damage depending on how high above he was when he launched the attack. I remember being able to instakill someone by diving them from the top of the map with my Q activated.
