Low level Fates for low level classes

[Odd]

Not to mention, those spells are weak and you need to do at least 30% of the damage in order to get gold.

That simply isn't true. When I do low level Fates as WHM, all I do is put aero on each mob, and I never get less than gold. Yes it's boring, but it's not hard by any means.
If what you're saying was true, only three people could get gold from boss fates. Also, GLD/PLD would never get gold since they do the lowest damage.
