If there is one thing I absolutely hated with a passion in other MMOs, it was the "everyday login reward" shit they pulled to "give people something to do". That's not doing anything! My freaking CAT can do that! And if you actually have a life, you won't even get the main rewards because you couldn't log in often enough, great.
I can totally get behind longer quests, trials and the like, something that takes longer but that I can still do at my own pace. Something that takes one hour each day for 8 days, or 8 hours in one day - totally fine. Something that ONLY works with one hour per day is not just excluding a lot of people, it's also the cheapest way ever to force players to log in even if they don't have the urge to play everyday.
