I can relate :)

I was usually high Onyx rating, the only thing higher than Onyx is Champion in Halo 5. The way it works is that the top 200 highest in Onyx ranking become Champions, there is only 200 at a time. If someone who is rank 201 ranks into 200 then he then takes the spot of that 200th person and the 200th person ranks down.

When I play Halo 5 in most game modes I play against Champions almost exclusively on the enemy team and on my team. ESPECIALLY SWAT, constantly playing against only Champions.

The thing that pisses me off is the higher up in Onyx I got the longer it took for me to find a game to play lol.

Halo 5 and 4 stats are down due to the new Infinite game that came out(total trash multiplayer and I hate it) that ruined all the APIs or I would post a link.

Battlefield tracker is still working currently so I could show you some of my stats on there.

My K/D and score per minute would be a lot higher in Battlefield IF I didn't typically play large maps where there are lulls in activity/nothing happening/have to run to the next point/area/getting slaughtered by vehicles and extra deaths from trying to play the objective. Would probably be in top 1%.
