So, Next V-Day is Heartseeker Twitch, pls?
Only he and Quinn are left, and I think both have hilarious potential, but I love my rat so.
Twitch: Hearts appear over head until it finally become one giant heart with an arrow threw it for 6 stacks. His W could be perfume "l'eau de toilette" His Ult could have pink sprays with hearts tailing the shots. His e could have the animation of red hearts "ripped" from the enemy champions.
Like Varus, he could have no shirt, wear typical cupid garb, a brown belt for his love potions, etc. His xbow could resemble Vayne's, and his goggles could be heart shaped!
Quinn isn't played to the part of a "typical female fantasy" in her design, but someone else posted some ideas I'll copy: Her valor's mark could be a heart ("ACCEPT MY LOVE") THe crossbow is small, but pink bolts are a nice touch.
Valor could be a dove, and his animations could blind with heart shape covering the enemy's head (instead of the black blind indicator)
I prefer the rat, but I think next year's heartseeker could be awesome.
(Note, I assume that since Heartseeker skins have only included bow/arrow champs, I'm limiting the possibilities to the above only.)
