Looking to spend some of my IP on a 3150/4800 Champ. Not interested in the cheaper ones currently because I could save up for them much quicker, and I own most of them already.
I am usually top or mid, but play everything. Just not as good at the other roles. That being said it is mostly mids left in that price range I don't own.
4800: Galio, Swain, Kennen, Maokai
3150: Anivia, Xin Zhao, Gragas, Lux, LeBlanc, Kassadin, Gangplank, Sona, Corki
Galio - Played 2 bot games with him during free week, didn't get to try in an actual game. Seems cool.
Lux - Only played her once and I don't completely recall how I liked the experience, but it wasn't a negative one.
Anivia - Played her a handful of times during last free week. I can see myself liking her if I got good with her but I tend to shy away from champs so mana hungry.
Gangplank - Tried him a few times as well, wasn't really impressed but I guess he would be nice to have in my pool if needed.
The others I have never personally played, but have seen enough of to be interested in.
Sona would probably be a good pick honestly because I only really have Leona/Janna/Lulu for supports, and I don't enjoy Janna that much. That being said I rarely play the role so it is not a high priority.
Added Corki to the list. I have only played him once and it was a realllly bad time. Lost the lane rather badly, but he also felt really weird to play, so it wasn't a great experience.
That being said I don't have many AD carries at all(really only play Ez and Kog) and he seems to be very good in the right hands.
