If you are the only one doing FATEs in a zone, it shouldn't be taking 15 minutes to solo a FATE. FATEs adjust difficulty depending on how many people are doing them currently. Less people doing them = less HP boss fates have/less enemies needed for completion/less items turned in for completion. If you are truly the only person doing FATEs in the zone, one should take you 3-5 minutes, tops. That means 7 toad skins every 5 minutes, guaranteed. Don't have to fight toads. Don't even have to do FATEs in Labyrinthos. Not to mention even if you're getting synched down in level doing them, it's just like any other synch'd content. Your level might be reduced, but the stats on the armor not nearly as reduced. If you're geared up, you should be able to clear a lower level FATE easily. Hell, if you're having that much trouble, you don't even have to do Endwalker zones, you can go back to Shadowbringers zones and still effectively get 6 toad skins per FATE. If you're upset about not killing toads...why? What did toads ever do to you? Do you have some sort of deep seated hatred for toads? ...wait...this gives me an idea for a glam! The toad head and some sort of super hero looking outfit, dyed all black. I am the croak...I! AM! TOADMAN!

*cough* Anyway, given how obtuse you're being about the whole thing, I'm guessing you're not looking for actual solutions. You want to complain. Or are trolling. Which is whatever, it's the Final Fantasy XIV Official Forums, that's what people do here, but let's call a spade a spade.
