Froggy and I worked out that as we mostly solo up in QM on tanks and healers, we are more likely to be matched agasint 5 mans as they usually have these essential roles in their comp. Frog’s on the EU server (me US) and it even happens to him on a regular basis.
I’ve beaten 5 mans sometimes, but more often than not it’s usually not a fun experience. I’m not sure what can be done though.
