Hide And Seek

What percent of Hide and Seek games are won by the seekers? Because I'm fairly certain that it's a lot lower than 50%; I'd guess maybe 20%. The thing is, with the standard accepted rules, the hiders should almost never lose. In the ban phase, there are maybe six or seven ban-worthy seekers (Diana, Rammus, Yi, Twisted Fate, Ashe, Warwick), since a seeker has to combine high mobility with high damage and strong cc, a rare combination. Seekers, on the other hand, only need mobility; there are upwards of thirty bannable seekers. The other main issue is that seekers need to split their gold evenly between offense and mobility, but hiders can go straight into mobility items; even with killl gold, the passive gold on the map ensures that in terms of mobility, the seekers are sort of screwed. Anyway, in your experience, what percent of Hide and Seek games are won by the seekers?
