I still think the best way that can challenge the monotomy is the drop daily/weekly limits and just make them monthly. If you feel like grinding lore for a day or 2, go for it. or if you feel like spending a few days crafting/gathering for scrips, or doing beast tribes, or going roulette crazy, or concentrating on some new content, or whatever you like. Then rather than think "oh, I HAVE do do A,B and C and D today", I can log in and think to myself, "hmmm, what do I feel like doing?" I doubt this would save any play time at all, and there's still a mountain to do, it's just not so linear/same old day after day.
