OWE travelling Qatar Business Class and transiting through Doha.

OWE travelling Qatar Business Class and transiting through Doha. Just trying to work out what lounges I can enter. Am i correct in assuming that the Doha First class lounge is ONLY for first class passengers? So even though I'm a OWE I can only access the business lounge? Has anyone experinced this? Also do AusBT want to do a concise article to summarise Qatar's confusing lounge policies? Thanks guys.

Rule of thumb with QR: Suspend all OW lounge rules, when encountering QR operated lounges. 

Upshot:

1. Only fly QR Business or First
2. Your OWE or OWS status is pretty much useless for real premium lounge purposes when travelling QR Economy
3. DOH is not really OW hub for the purposes of Economy class travel
