Groups get priority over a single person. Always been this way. Then it gets to Tanks and Healers because those are in shorter supply then DPS.

So if you join a queue at reset by yourself and a bigger group joins a queue they get priority over you. And if it's say 2 DPS they just need to match up with a Healer and Tank instead of DPS. And if you are a DPS those slots are already filled.

It's not abuse. What you are experiencing is entitlement. Yours specifically.
