Picks/Hovers/Bans
Many times nowadays, people complain about the current mechanics of League in that bans trump hovers, and pick order exists. While pick order likely can't be solved in ranked play, due to having to have some sort of objective and impartial method of deciding who picks first, the other issue is one I feel only makes logical sense.
Nobody forced Riot to make bans take priority over desired play champions. But, when you consider that there's 140+ champions in League, and that if someone doesn't want to play against or with one of those, the player who desired to play that champion can always play another... It only makes logical sense.
Does this open the door for trolling by banning hovered champions? Sure. Nobody denies that. Is the alternative (hovered champions take priority over being allowed to ban that champion) any better? Hell no. Not only are the exact same troll cases present, it opens up to a lack of team cohesion when you factor in that players could hover completely inappropriate champions for their role just to prevent them from being banned and thus letting the enemy team pick them.
One has to take priority over the other, and I think Riot has made the only logical decision. I'd love to see people discuss though, as I'm more than willing to admit there may be things I'm not considering.
