A Summoner Champion!?

I think Riot should make a Summoner Champion! A champ that only summons when using abilities! The best way I can help your imagination is something like Final Fantasy. The summons could be like 5-10 seconds long. You could make them have an offensive summon I.E Shiva/Infrit. Or have a support/defensive summon that heals your team or increase the Armor, MR, Heath Reg, ect. I think having a s champ that just uses summons for abilities would be pretty amazing! :D
