Can't seem to get games for tier 4+ is that normal?

just played a legendary with very short que time. However it is monday at 9pm central.

We've tried legendary a bunch of times, had to quit after 5 minute wait times.

You quit after waiting for 5 minutes, jeez, your not patient. Sometime you miss the queue and must wait a good 10+ minutes to even enter recruit or veteran matches.

If takes more than 15 minutes to enter matches, then you probably should try lower tier matches. but 5 minutes is not a long waiting time per Dreadnought standard, its the average.
