well I've played a lot to see how the game mode was working out
its actually pretty simple stay near a power ammo box get behind cover and shoot who ever tries to get it it basicly lets you at top 4.
how you can get first place is basicly get legend of acrius get one power and rotate the power ammos. Game mode is pretty easy and I was basicly in top 2 most of the time...
Some maps are like you said too small for 8 ppl but when 2 ppl leave the game mode becames more consistent and fun so I take my word back having 6 is better than having 8 on smaller maps. But on big maps 6 wasn't enough I mean I running around for a minute to find a fight for it to end right when I get there. Also is it me or the que times are hell on pc. ps4 was fine I guess but longer than usual still. And I was getting matched up against the same ppl I think for 10 hour gameplay I only met 30 or so different individuals thats not good on pc it was worse I was getting matched up against the same ppl again and again... and still waiting a hell of a que time...
And I waited 1 hour for a competitive game mode and still couldn't find it on pc... I assume pc population is a lot worse than ps4.
