I completed that objective for my Hunter armour - and it was a painful experience, especially on PC with the amount of cheating/hacking going on. It took about 4/5 hours to win just 7 games. I had hoped that by doing the final armour objectives on one character, those same final objective completions would transfer to the next. They don’t! As soon as I learned this, I just turned the game off. Which is a shame because I would have liked the armour on my alts.
