The part of mentor roulette where it has so many duties is the point. Mentors already abuse the system to try to get as many easy duties as possible on their way to the mount, giving them a guaranteed way to get it while never having to actually pop any underplayed duties would defeat the whole purpose of the queue.

Letting free trial players make PFs is a no go. It won't happen. It was removed because of the RMT ad spam from f2p characters that would get made, get banned for advertising clear sales, then come back in a new trial account. There's a reason the restriction is there.

Also EX content is not actually that hard. Old fights up to stormood have single digit numbers of mechanics to learn with the exception of nidhogg and I've cleared that in DF just fine before. Mentors just love to complain about getting alliance raids, ex fights, and msq because it hurts their speed farming for the mount and titles. Then they wonder why mentors get a bad name when most of the experiences people have with them are either abandoning at the start of duties or rushing everyone through for more roulette completions.
