- If you can't DPS then DO NOT pick DPS!
- If you can't heal then DO NOT pick heal!
- If you can't tank then DO NOT pick tank!
- If you are forced into role you can't do well say something, people will swap around.
What is so hard about that?

Just had game where healers were too busy trying to pad their KDR stats that they totally forgot to do whole healing part. Had to stalk and harass Zen constantly to get him give me healing orb so me, teams 2nd tank, would RIP when enemy sneezed at my direction.
So frustrating.
