Guild Wars 2

It’s not even needed. WoW has used a rating system similar to gw2’s pips/divisions and its worked fine for years. They haven’t attempted to manipulate matches further with an algorithm which is designed to “calculate a players skill level and match them up w/players of similar skill”.

How does one define “skill” exactly in the sense of an algorithm? That is such a complex variable that you can’t even attempt to control all the variables, and thus MMR is useless and isn’t accomplishing what it was designed to do.

Removing it would at least take the blame off of a-net, and people would just assume “Oh well, I got unlucky, or the enemy team/players were much better than me” if they were to lose, and at least not feel like the system was rigged against them (which it is).

Not having a matchmaking algorithm hasn’t hurt WoW e-sports at all. And for an e-sports scene its the most successful of all MMO’s
