Actually yes. It's easy to get the purple one. Blue and green were just useless.
It was a good move to remove them and leave only purple.
Yeah, you are right and we basically removed them from all rewards for that reason. After Gunsmith the balance of those cards had changed significantly to the point where only the Purple XP cards were worthwhile. It may still be something we change in the future, but for now it seems like the Purple XP cards are worthwhile as a small reward and useful overall for leveling up weapons.
