I know a lot of CG shills will say that we were never told that the assault battles were going to stay at 2 days. They also never said they weren't, it was actually never announced that they would be 2 days at all IIR, even for the holiday.
But either way, my main frustration is that the update yesterday was considered minor and there was no mention of this being changed.
But as you can see from the data mine, this was discovered:
And while you may say this won't effect tomorrows AB, or that this wasn't in the recent update, this update also included the player title "to me she is royalty." which was announced by Doja along with a screenshot.
Again, while this isn't a huge deal, its just another reminder of the lack of communication. It's also another instance of CG changing something everyone appreciated and benefited from. IMO these being 2 days really helped with the kyro farm that has become a huge grind along with the cost increase in the shard store.
