Catalyst Clash-Class and Ascendant Crystals Question
The T4 Basic and T1 Alpha arenas have been very useful. In a very reasonable amount of fights I'm able to farm 3 T1 alphas, and 1 or 2 T4 basics. This is in addition to a decent amount of units and a few other goodies as well. When it comes to the Catalyst Clash-Class, the Catalyst are not included in the milestones so chances are you're only going to get Ascendant crystals. They seem to primarily drop ISO, which is cool, but it doesn't seem to be worth the grind. Am I missing something? Are these crystals really good and I'm just over looking it or is this one of those arenas that could be considered skipable?
