No algorithm will save you from this... The fact is that There are just 3 tanks 3 healers and.... 9 DPS. So we got 3 times DPS in compare with tanks and healers. Besides that everyone and their mom's playing SAM and RDM. Besides that... Few White Mages and few DRKs and WARs. So the DPS chances to enter fast is close to none if you queue alone. You would need a friend tank/healer to push you in.
