Without weighing in on game mechanics like AOE/Friendly Fire, I want to answer the post question from another angle...
The thing about Game of Thrones Ascent that long-time players miss most now that GOTA has ended is the Alliance vs Alliance phases that occurred at regular intervals. Phases lasted various lengths of time (24hours to 7 days) and were always being tweaked by devs to make them fairer & more exciting.
Each phase had overall winning alliances and players - points accumulated by succeeding at attacks against rival alliances, but players could use a wide variety of attacks (fight, harrass, steal, swindle, sabotage...), as well as actions that supported friendly alliances (barter, repair...). Garrisons in alliance camps defended against actions, but troops lost effectiveness as they got wounded, and eventually died and needed to be replaced or resurrected at cost.
There were prizes for alliance eminence in the various types of actions that changed phase to phase - so, a particular phase might have special rewards for the Swindlers or the Sabs or the Skirmishers - so different playing styles all had a way to enjoy themselves (something Fractured gets, which I truly appreciate!)
Not sure how this would map onto Fractured, but the introduction of AvA phases was a complete game-changer in what had been up to that point a fairly generic 2d RPG/Builder game with fabu graphix. I had never before played an online game for more than a few months, but played GOTA for over 6 years and there's still a fb page full of ppl in mourning, looking for a similar experience and not finding it anywhere.
