Yes and no.

No, duty finder expert roulette is not fucking fun. I die a little more inside every time I have to do it.

Yes, expert roulette with a premade group of 4 can be fun. Try it as three warriors and a scholar. Or four warriors if you're feeling particularly badass. Or three monks and an astrologian. Or just a standard party, but pull EVERYTHING at once, door to door. Who cares if you wipe, you're among friends. Just see if you can do it. Try new things, don't just stick to The Strat (tm).
