Are you guys serious? Solo EXP is already PRETTY DAMN FAST with leves and guardian's aspect. What do you want? For it to be as fast as a group EXP party? Lv50 in a day since a week is way too long?

Don't convince the devs to baby this game up to cater to your 20 minutes of playtime per day please. You can complain about EXP rates in 2004 FFXI but definitely not in this game. It's easy enough as it is.
