Things that I'd like to see (PVE)

So I've been playing a lot of other games lately in addition to league and have been seeing a lot of neat things that i would like to see in league. Some of them are starting to be implemented already (PVE Missions) but id love to see more. In this case I'm drawing from the Strife, which i believe in the one episode they produced, did it right. I would love to sit down with some friends and play through some event in Demacia where the forces of Noxus are attacking, and you as Garen, Lux, and J4 have to fight through the streets driving them back until you get to there camp where you have to fight an epic battle versus Darius. Imagine the behind the scenes characters and the lore that we could learn about while playing with people already know, or even ones we don't. Imagine if instead of Gangplank dying in the Bilgewater event, a new champion was released during the event only in the event; then later when the event (or episode in the case of this concept) had been out for a while, the new champion was released for PVP. This would also be an awesome way to give rewards to players, like icons or an emote. As much as the PVP of league is amazing and I have sunk HOURS into it, but things like the Star Gurdian event or Strifes "Adventure" is what I would like to see more of. I like to be able to sit down and enjoy more of the Runterra environment without it just being in the Rift/Treeline.
