The boosts are based on "day" expiration instead of "win" expiration, which seems really crumby to expect "new" players to make the most of these boosts. I was considering gifting this to my brother, but I feel like the boosts would be wasted after a single day of trying to show him the ropes and what not in custom games. It would be nice for the boosts to be 10 wins or something.
Also, the champions given are really cheesy. I understand the decision to start them on "easy" champions, but I would say a combination of 3/5 of these champions are "free" every week as it is. It would be COOL if they also received an exciting champion with low difficulty curve as well. Someone like Darius, Morde, Riven, or Shyvana for example.
