The issue isn't with skill to beating events... The issue is when purchasing chests in events the cards say "permanent boost" but it is only able to be used in the event and not in the main game. When first playing you don't realize it so you spend money thinking you can use the permanent boosts in the main game but they go away. So, I wasted money thinking I'd have permanent boosts in the main game but they went away... So they aren't permanent. They are misleading...
