I like gathering. But I hate leves. So, for me, the Diadem is still 100 times better. It's an actual zone that has mounts, and when you fill the bar, you get to bazooka enemies and get more materials. It's just night and day.
Crafting is never going to be fixed for me. I've always hated it. Too convaluted for too little gain. I like being able to craft things for myself like gear and glamor, but the stat caps and the min maxing of it all turned me off it completely. Now I just keep them to 100 and get my master books and 100% NQ glamours and go on with my life. Once I got to master crafts, I knew I wasn't going to get gold rank anymore and just kinda gave up.
At the end of the day, I've set myself up to get the rewards I want, and then I'm abandoning it until new rewards come out. I don't care about relics unless they look cool, so I'm really just cred farming.
