Oh look I queued into a counter comp and went 0-6, give me my -200 points big daddy blizzo just because of RNG and your bad matchmaking system. Why is this okay??
You can target a rating by doing a key. If I target a “+16 X” ill get “X points”. You can literally calculate what you’ll get by doing a dungeon that has scripted mechanics.
Dynamnic arena rating matches the dynamic nature of your opponent.
Static M+ iO matches the static nature of the challenge.
