Someone might have suggested this before, sorry if it is a rehashed idea, I haven't seen it yet. I was having a discussion in my guild about someone soloing the Rancor and whether it matters. I was thinking to myself, it's kind of counterintuitive that we have a game mode where we are essentially competing against our own guildmates. It's not the end of the world, but I think there might be a better way.
What if we had a new raid where the awards/prizes increased the more total damage a guild could do over a set period of time? So everyone gives it their all for 2 days or whatever the time is and then prize ranks are based on damage, but the prize tiers also increase as the guild as a whole does more damage. You get better prizes the more damage you do relative to other guildmates, but you also all get better prizes the more damage everyone does. Win-win.
Before you say that is territory battles, it really isn't. TB, you end up deploying a ton of good teams that do no damage and once you complete a mission, you're done, you don't get to hit until your team is defeated.
