Primal Extreme non synced group?

So basically I love primal battles and have tried to do all the extreme ones - but have always been in stupid groups where someone will rage quit forcing the group to disband.

I would love to do the entire extreme fights - mainly to get the achievements and say I have accomplished them within the Game, just I cannot state how annoying it is to find a group (after upwards of 60 minutes) to have someone quit after the first try.

For the purpose of getting the entire extreme primal catalogue done, I am looking to join or form a group that will be willing to do friendly and fun primal battles un synced so as to make it easier to achieve, or perhaps synced at times too.

Is this something plausible, or shall I just continue to struggle with bad duty finder groups.

Thanks

try and create parties on PF with "this and this unsynced, looking for a clear". That alone should get you a group. :)
We do unsynced primals and coils all the time on Thursdays, but that's normally for guildies, still if I see PFs that just need help with a clear I tend to jump in.

Perhaps I could find someone looking for it then, and then jump in. I didn't know that was even a thing. Thanks
