whoever first picks tristana wins

And whoever bans Tristana doesn't have to deal with her. Every player has their own ban.

If you can't deal with a trist you shouldn't be playing bot lane.

I actually prefer to play against rather than with a Tristana when solo queing support because they tend to be predictable, overaggressive and their supports are basically swept under the rug.

Dude, no that's false ! Imagine if the 2nd pick is ... that makes the game balanced =)
