now that we've seen a jungling marksman, how about a mid-lane tank?
a champion to abuse mid-lane's vast resources, become extremely fat and scale into the heavens
i'd like a champion like that to be an anti-siege zone control god who claims an area just by being there
Sion/Maokai almost fits but he's not as specialized as I'd want
EDIT: Some misconceptions in the replies, let me clear up my vision here: I'm not talking about a mage that happens to build tanky. A full on pure tank If I had a vision for a mid-lane tank, it's be a tower champion, just this ridiculously tall champ whose greatest niche is standing it's ground and defying traditional positioning
A champion who declares to the enemy team "if you want to get this objective YOU GOTTA GO THROUGH ME", not just in sieging scenarios, but also dragon, baron, or even as a final incentive not to dive Heimerdinger
The existence of a pure tank in the midlane means teams can put AP in the top or jungle more comfortably, which is why this niche is important
