Back again, I'll try to be more active now and check the other threads.
I'm glad that Nue and Nazrin are here in the global version. It's been ages since we last had another UFO character join. Peacekeeper Reisen is also here meaning space Kaguya will be very soon too.
For the the phantasm stage in the arena, I couldn't be bothered playing through it. Like you guys said, the amount of damage we do compared to how much HP they have is ridiculous. The rewards don't seem worth enough to spend that much time.
I also don't want to keep grinding for those rare cards. Even with the increased drop rate, they still might not appear after 100 battles. I didn't even know what purple heart was until people mentioned the farming method. I wouldn't try it at all even if it meant I could get the cards quicker. The meta doesn't matter much to me either. I just like having as many characters as I can, but still use my favourites.
At least there is the story update to look forward to.
