I heartily agree with Bluie's assessment. I think my favorite part of the Armor DLC is the new wild area, as most of my time there going forward is going to be exploring and catching.
I think Serebii is working on the Diglett collecting last time I looked, but it kind of reminds me of trying to find all the Zygarde pieces again, ugh.
Has anyone tried the Zeraora raids yet? The very first one I came across was a five star square shiny beast of a Pokemon. It wiped out all four battlers with one move! I tried several other times, some in different spots or online with my lightning rod Rhydon, level 99, but still got wiped out with close combat.

Eventually I was able to beat a 3 star one, but wow, I am not sure what strategies should be used to stand a chance to the higher level ones.
