https://github.com/chromiecraft/chromiecraft/issues/5992
### What client do you play on?

### Content Phase:

### Current Behaviour

As a solo player, queueing for skirmishes via command .lla queue or battlemaster NPC shows that you are queued for rated on the icon near minimap.

### Expected Blizzlike Behaviour

If you queue for unrated it should say you're queued for unrated.

### Steps to reproduce the problem

1. Be an ungrouped player
2. type command .lla queue / queue skirmish via arena battlemaster NPC
3. observe incorrect tooltip on your minimap.

ChromieCraft

Start by tracing the module's handling of the `.lla queue` command and the arena battlemaster NPC path for solo skirmish queues. Reproduce the issue with an ungrouped Alliance player and inspect how the minimap queue tooltip distinguishes rated from unrated; done means the skirmish queue is shown as unrated.
