Solo/Duo ranked
I think that the duo option should not be included as
- helps boosting
- gives the people duoing a not indifferent advantage over those that are not (also due to the lack of voice chat)
- in high elo it is not possible to duo so i do not see why it should be possible in lower
Do not know right now if there are any other reason, well that's just my opinion let me know what you all think about it.
