Ive been trying to do the Proving Grounds GM seriously all day, have only gone up to the beginning of the second part before someone leaves because someone died (you know there are revives). No one wants to commit to actually staying through the finish the strike, just once. Its frustrating people act this way.
Not every GM needs to be a speedrun and most people I've seen have absolutely no idea what they are doing and not even equipping the proper mods. Within the first 5mins someone just leaves. Even when the strike begins, they bounce. There are guides and such and I'm happy to try and teach people but its always ends up in damnation.
