Aside from the instruments, I'm the same.
I am focusing on leveling every job to max so i am in equal terms with everyone else next expansion. This is involving roulettes, beast tribes and dungeoning.
I got rank 8 in Bozja and haven't returned. I honestly don't like how it's structured.
I would return once i catch all jobs up to 70+, but i doubt it will be active by then. I'm not a fan of this type of content. If it's gonna be party based, they should group you with a party when you go in. But, it would be best if it was organic with people just joining in like in guild wars 2. Like, the potencial is there but the execution is poor.
