How Events should work

For a while, I've had an idea about how events should work. Most of it's the same but there are some differences in my version.

1. New Champion based on said event- They already do this so it's nothing new
2. Event themed skin for unrelated champion- Like Guardian of the Sands Kha'zix for the Shurima Event
3. Temporary game mode related to the Event- Like the Shurima Event had Ascension
4. Ultimate Skin for related Champion- Ex: If there were a Void event, Kog'maw could get an ultimate skin
5. Icons- Already done
6. Ward Skins- Rito Pls

That's all I wanted to share. Riot I hope you consider this. It will make the events way more hype and enjoyable. And you could make more money from it as well. Please and thank you.
