All they have to do is add Domain Invasion to the "Region Info" tab with a little dragon icon on each of the 3 zones, which indicates where the current DI is and the countdown. It would be so easy to implement.
Except that when things that are critical in regards to time are involved... these menus fail. Can't count the times I used to go to Campaign battles that were active according to the map, but they had ended minutes before and yet the map hadn't updated.
Sadly, Unity is a ***system (mostly due to gear boosts and useful trusts being gated behind only a few unities leading to overcrowding), but there seems to be
NO INTENTION OF THEM FIXING IT at this point. They are doubling-down on "this is working fine" with their new content being geared (literally "gear") towards Unity equipment so if they were going to change... *sigh* it should have been earlier.
I'm getting a very pankration/evolith-etching vibe from the Unity stuff, even as they tweak the unity gear, in that I feel like it is just going to be abandoned as far as solutions to the system of notifications and useful trust distribution goes.
The gear should just be maxed stats as if you were in the first place unity and all unity leader trusts should just be unlocked.
