why is oqueue better than wow finder ?

Hi,

maybe its silly question but i would like to know advantages of oqueue. Many pple dont know Other raids funciton so they downloading oqueue, at least i think so.

Till now i just find problem with oqueue like, wait list full, seriously wtf ? Why cap? Raid lockout problem, yes update wont fix it. Bad role, even when i tick qualified. Hi lvl cap, not always its about ilvl if i see there for 2 hrs how pple looking for 1 healer, and you cant wrote them thats wrong.

Next problem when group is full they are still queued.

Next problem i cannot join there as single, group person so some1 who is finding something can invite me.

World bosses in raid tab, i asume you can give there World boss tab.

Sorting raids by category if i wanna see SoO im rly not interested in ondasta or ToT.

Battle tag, this system i think is pretty misserable to share your ID, yes you can delete it, for 50% times there will always stay pple in my friend list i have to delete them manualy.

Actually i see there just 1 pro and its comunication canal even when pple wont share it for some reason, or when i play with french guys.

So i would like to know why its better or if its just because pple dont know other raids in wow. (btw its O -> raid -> other raid)
