Backwards incompatible changes, it seems.
https://api.torn.com/faction/8819?selections=attacks (and attacksfull) now seem to return the oldest 100/1k results by default. Previous behaviour returned the most recent 1k/10k which seems to make more sense as a default.
Can we please retain the previous ordering when the from/to params aren't specified?
Or is there some param I can specify to provide sorting instructions?
