I've been burnt out as well. I'm usually logging in once every two weeks but it is no longer than 30 minutes. I was hoping for a good grind in OC. But that was just roulette spam which I recently completed 3 weeks ago and have slowed down logging in since.

I tried the deep dungeon and got bored of it because its like previous deep dungeons. During Shadownbringers and Stormblood this was the time where I was knee deep in exploration content but they didnt add anything in 7.3 for exploration content. I was burnt out on the crafting and gathering exploration style content. I've been doing what Yoshi P recommends and that is playing other games.
