Heh, you focus on that, but you missed this?

Certain 3rd party tools allowed players to capture and show the packets sent from the servers, earlier than they should be shown. (note: They are talking about 3rd party tools calling out Gaol targets in Ultimate before they even show up on the screen). However, they don't think it was that crucial of a problem, because that phase takes place early on in the battle.

To counter this in future content, they will need to add another layer of protection. They want to change the timing and how they send the packets, and also improve how the effects/animations allow you to detect the mechanics, in order to confuse those 3rd party tools.
You should be worried they are going to break all the third party stuff due to ultimate raiders. Hopefully it wont be all content.
