If you can't no-life during first 2-3 weekfs after m+ release you will find a lot of problem finding m+ groups. Ppl don't care that you have completed 5 +10 runs already - you need 1k score. I am too lazy to finish every +10 dugenon in first few days because m+ is fine until you spam it and it become boring.
If i am creating m+ group for pure pve players i rly look at this raider.io shit points but when i see someone if skilled pvp player (2.4k+ or 2.6k+ bfa - rating inflation) i instant invite them. Rly, this points doesn't prove someone is better than player with less points. If you want to check someone check them correctly.
There is huge difference between pure pve player and player who play both modes at decent level.
