Unfortunately they replaced them with a paid pass system in what's basically a paid game, and it's really disappointing that they've reworked the monetary side of the game multiple times since closed alpha while every other part of the game j can think of has had ducttape fixes or has just been ignored (offensive abilities, bloated menu system, obtuse scoreboard/end of match powerpoint, champion balance).
