To be honest even for levelling combat classes, I quite like them and I don't think they're as bad as people say. I use them relatively frequently, netting a bunch of EXP every time and having a variety of objectives to complete. Places like Whitebrim are great for it, or the Observatorium if your level is lower. Sometimes when I'm just playing the game casually, chatting to people who are in different areas or sometimes even playing different games over a headset, it's nice to do Levequests. Having them give more EXP would make them too good I think, so I'd be more in favour of increasing allowances. It was 4/12 hours in 1.0, right? Even that would be a start.

Even now though, they're still more fun than laggy Coerthas FATE grinding.
