Blue team's winrate jumped to 55% since the "10 bans" release

Source: http://www.leagueofgraphs.com/rankings/blue-vs-red I wonder what it could be linked to: --- More OP champs banned -> only one or two OP champs available and blue team gets to pick it first ? Also a lot of OPs champs can be played top. --- Ganking top is easier for blue team due to the tribush. (and ganking bot is easier for red team). Could this means that a fed top can carry a game more easily than a fed bot ? Indeed the "Champions Winrate difference" array shows a lot of Tops with high winrate difference --- This also could be proved by the fact that rift herald is more killed by the blue team : the jungler has more facility with the ganks top and kills herald just after a gank. (Baron, on the other side is more killed by red team but, since it's done later in the game, the impact of the jungler is very different there)

The easy way to figure it out is to switch which side picks first for a while. If the winrate flips, then we know it's pick order. If not, we know it's map related. Best case scenario: blue currently has both map and pick advantage, and flipping who picks first brings the winrate closer to 50%
