I think most people prefer to solo because of the following reasons;

1. Depending on the class, it is much faster to level.

2. You can kill on your own time, meaning if you're doing housework or studying, you can afk whenever you need and it won't effect a group. (This is great if you're soloing a mob on a 6-min timer)

3. You don't need to split loot = more pp for you.

Don't get me wrong, I love to group, but it's hard to go from getting 1-2% per kill with literally no downtime, to getting 10% in 2 hours of grouping. I usually group when I just want some interaction lol
