New champions -- Stealth / Happy?
So! As of now, we only have two stealth champions (three, if you count Teemo -- no, Rengar doesn't count). I just really love the idea of stealth, being able to pop behind enemy teams and assassinate their backline (Shaco, Twitch), or just being able to walk around people and have them not even know I'm there until I'm ready to attack (Eve). So, for some champion down the line, can we have like... a toggled stealth? It's a mix of Shaco and Eve (semi-permanent), and it would be one of their abilities. Could even have it drain mana while active, and maybe turn drained mana into a bonus of some kind.
One other request I have is a transforming champ, like Nid / Jayce, but something like a spellblade. :3 Fast/agile, with high-speed combos that involve R a lot more than Jayce or Nid do.
Annnnd, last request, is a champion that's more light-hearted and optimistic, like Braum, Trist, and so on. You just can't play either of those two and be in a bad mood, especially Braum. xD Lately the champions and reworks are so depressing and serious, we need a bit of comic relief and/or a lighter-hearted champ that makes you feel good, instead of making everything seem darker.
the Plague Rat who is a stealth using marksman/assassin to be a stealth user?! Blasphemy! He even has resets on his Ambush now when he kills someone who had his passive on them when they died! T_T
(its temporary and its on LeBlanc's passive when it procs) 
...
well the others have light healing but they don't amount to much in team fights when your team needs major supporting, i mean 
have decent cc effects but there heals are just minor buffs.
