Reaver crashed out of a game, so his score is off of 9 games. Nickmercs is also playing against console people. It isn't the same thing comparing PC to Console. They should run separate tournaments.
Lastly Battleground games will almost certainly never work as a really competitive game play style. It's too RNG. Throw in the defining mechanic of fortnite, building, and you end up with last weeks game. Roofing and Flooring with Bob Vila. Enjoy the view as your favorite player spends 99.9% of his time crouched in a closet looking at roofing or flooring.
If Reaver didn't crash out of game 9, and go on tilt on game 10, he most likely would have finished 2nd, or close 3rd to Faze Cloak. About 2 minutes into game 9, his monitor shut off, and then his computer started making crazy noises and it shut down. He had seen one guy, and killed him, and was in a completely safe location. So he pulled 1 frag out of a game, when he was averaging just over 17 pts points per game to that point. He freaked out and ended up spazzing out and killing himself via Tim damage in his 10th game. I think he took 8 points out of his final 2 games after the crash, when he was averaging 17.25 per game over 8. If you take his 139 after 8 games total, and say, give him 15 per game over the final 2, which is below his overall average per game over 8, he'd have ended up with 169.
The fact your NickMercs guy did so well, also explains why IDropz did what he did with a mouse and keyboard. The standard of play on console is so hilariously low. Yes, NickMercs is one of the best players on console, but his doesn't build, he doesn't try to take high ground, he just runs along the ground and kills people who are fecking terrible.
