So here's the list of things, themes and champion features I think we lack in League and sure wait for Riot to give us in the future:
--- old lady - this one is requested from time to time here on Boards. A lot of players would like a bad ass grandma or an old witch
--- fat female champion - we have Gragas as the only fat champion out of almost 140, why not add another one? There was also a concept for a Storm lady some time ago that I liked http://i.imgur.com/grekodz.jpg -- http://i.imgur.com/J3oPJVl.png
--- a male child - so far we have 3 girls in LoL, Lulu, Annie and Zoe. Why not a boy champ?
--- a portal themed champ - redirect enemy and/or ally spells with 2 portals, go in and out of portls, mobile, travel through map. Think Yugo from Wakfu, Jumper, Portal games. Very unlikely since we already have Bard E and Zoe R
--- a gas/swarm champ
--- a parasite champ - can merge with ally and/or enemy or maybe take control?
--- an offensive water mage - we have Nami as the only water based champ so far, why not an offensive mage? We have few fire and ice champ after all
--- a sound/voice champ - a Banshee or just a champ that uses sounds to attack. Sona is and Aura mage, not a sound one
--- a mirror/disuise champ - can copy enemy spells, take his form. For me it would be ideal LeBlank rework but LB has a lot of fans so probably won't happen
--- a Void supp champ - support is the only role left without dedicated Void champ. I think it would fit with parasite theme
--- a Yordle jungler
--- an assasin Yordle - would be great if these two would be mixed, jungle assasin Yordle
--- an AD support - so far all supports scale with AP, even tank ones. Does Riot not make AD support since they would have to make a supp item just for him?
What do you guys think? Can we see any of these in the future?
