Yeah, I basically always 100% ban Eve just because the stealth mechanic. I mean, nobody buys pinks wards in soloqueue so she's gotta be banned. I also usually 100% ban nasus (unless I'm going to play him) because he's overpowered as hell. He doesn't lose lane because he can always level Spirit Fire up first if needed and clear from a huge distance. Sure his Q won't get stacked up as much but it can still get high enough. Even a mediocre Q stack is fine because Wither is still OP against ADCs and his Ult is doing constantly % damage.
My 3rd ban is always a toss up. Usually Lucian (I've fought waaaay too many strong lucians lately so I'm getting sick of him), Kassadin (Usually depends what our mid laner is playing, but Kass is scary strong atm), Fizz (Not as much anymore, but his burst is stupid strong) or Annie. (She's such an OP support...)
