Ive been playing this game for almost a year and it's getting boring nowadays. Rewarding system is a joke, why? Even if you land on good score/points on Faction War/Survivor, you will always get trash gold cards. Strengthening your collection is not easy and will require millions of souls thru a chance pack (most of it has a limit of 20). Still no actual PVP. Lots of useless variations of kards.
