I get that Yoshi loves jumping puzzles.

Not everyone does.

I spent over 40 cumulative hours trying to do the ones in Kugane, then he added another, and a very obnoxiously placed one too, right by the aetheryte.

Stop making the game so difficult for people with poor hand eye coordination. It's not fun to constantly fail at it only to see people dancing on the spot you're trying fruitlessly to reach.

Or at the very least, stop making it so you have to complete the stupid log in order to get the paintings! I know the paintings are all ugly because Square Enix thinks the only paint pigments in Eorzea are shades of Sepia, but paintings should be unlockable as you find them, not for completing your pokedex.
