Blind pick still labled as "summoners rift (beta)"

That's because it is still the beta; there are many changes coming. One including exits from the base in between mid and top/bot, only usable by that side's team. Meaning Blue team can go in and out of their entrance/exit, however red team cannot, and vice-versa

no, go to pvp > Classic > summoners rift. look at the description under blind pick, then look at description under draft and ranked. See the difference?
