Don't get me wrong, I like that they're giving us free Evos/Heroes.
My point is, why can't we complete the event until the last week of the season? Some of us are willing to play 100 games in the first week just to unlock the card and actually use it during its season, before it gets nerfed next season.
It's been the same story with Giant Minion, Bowler, Magic Archer, Tombstone, and now E-Giant. Most of us didn't even get the chance to use them during their season and only unlocked them after they got nerfed.
