If you are getting this game, dont spend your time on the arena. It is broken. You can face someone with ten more stars than you and still get penalized a lot. If you play against someone with the same ranking, but they pull out an attack 20 diamond card despite you being ahead and at 5 orbs, you still lose 5-7 stars. You can take 25min to get to a rank and lose it in 3. Please devs, fix the arena.
