Champions of League...

It's been season 4 since I first played League... There's interesting champs, but there's truly not a champ who I can say I truly main... I just haven't not found any champs other than Zilean, or Bard who's got these interesting mechanics that aren't so lack luster to play (My opinion). Before anyone says anything, it's not like other champs are bad or anything, I'm looking for interesting champs to play. I thought Ivern would be fun, he is, but his kit lacks something that makes it feel... Not so game changing for me. I think his ult should have been something interesting other than another annie-like ult. I also like champs who are like 50/50 such as Singed. Who can be countered or counterplay 50/50 instead of elevating from 0-100 in a flash. There's so many champs, I just wish I had this one specific champ where I can actually say, I MAIN THIS CHAMP proudly...
