Keeping harder content full queue only won't fix anything.if you played when it worked that way you'll likely know that many people complained about that and the fact they couldnt even try content without a full party.
And even in the farm parties it didn't always work out cos you.might have 30 ppl wanting to farm but split across 6 or 7 parties different parties in the party finder and none of them fill up.
Sophia and Zurvan were big for this. Especially when people wanted to do one tank only zurvan and all those parties in the finder already had a tank. And 2 or 3 other people. So you end up with 10 or 12 half filled groups and a tank who wants to do it then has to create yet another party that won't fill up because there a dozen of them in the pf already..
This is why people used raid finder just queue it up and go. To many parties in the party finder who knows which one to join..
If you want to get rid of raid finder the raid finder options need to be added to duty finder for both full parties and individual players...
There seems to be a very one sided argument that if you want to farm make a party finder for it.
Yet that very same argument can be applied to if you want to learn or practice make a party finder group for it.
The ability to solo queue was not a by product of the raid finder it was its intended purpose. To allow players who didn't have the time to form statics or recruit parties to access the content with a reasonable chance of success. Because players were simply not using the duty finder at all.
think I recall Yoshi said in an article a while ago the addition of raid finder gave Sophia the highest in patch clear rates of any extreme primal to date.. It was also a big factor in the increased clear rates seen in creator savage. more especially 9s and 10s Because it allowed people to participate and succeed in content without preformed parties.
I cleared Soph ex in patch using raid finder with 1 friend. no pre made party, no nothing just his drg my ninja hit practice and go.... if the raid finder wasn't there i wouldn't have done it that patch because it would have been locked to full parties only. i did the same with zurvan ex. again without a premade party.
the ability to queue this way was not a by product of the raid finder it was it's purpose... you cannot then take that ability away from players because if you do you're just going to put the system back into a state where people just don't touch it. (see what happened to coil / savage / thordan.. it was in the duty finder but noone would ever queue it because it was guaranteed to be a waste of time...
