Lets keep the names out of this...
I'm a little terrified to interject here, but I'm reading this and would like to get things back on track
The main issue -
Group A is saying 'insert name here' zone (trophy range 0-199) match-makes by different rules than any other trophy range - for whatever reason. May it be a glitch or design.
Group B is saying that is not the case. You are matched by the same rules that apply to trophy range 0-9,999
Group A's point is that once you cross a certain threshold you get different opponents
Group B's point is that there is no match-making difference there. The difference is because of the types of people attracted to that trophy range. The same rules apply under 199 trophies as they do above 199 trophies. It's just that 0-199 trophy range is bloated with high level THs looking to do the same as you
Sounds like group B is correct.
