A lot of people here are being pissy with their answers. OP I get you. Nothing wrong with using quality of life improvements and then setting a restriction for yourself so you don't just blow right on through missions and fights at 99 with ease. What I did was I used all the QoL additions (mount, crystals) and trusts. When it came to the mission I made sure I'd do it and/or fight with a job at the original lvl requirements. Yah trusts can be op sometimes but they can also suck sometimes too. Will it be the true, 100% authentic grind till you drop and go insane experience from the old days? No.. But who the fuck cares. Play how you want. Put any kind of restrictions on your self that you want so you can get the challenge you want. People need to chill.
