I'd say my best experience of this year would be progging/clearing Criterion dungeon wit da boys, and then making over 600 million gil in just a few days selling the mounts while it was fresh.

Worst experience was definitely Week 1 Abyssos prog. Getting locked out of parties for playing PLD for the second tier in a row was just bullshit of the highest order. Part of me is kind of worried they're going to end up pulling a Creator and massively under-tune the final tier of EW to compensate, though.
