Not really against it, but I like incidents a lot better. Treasure Hunt had you thinking about the game all day long and didn't work well with my schedule. Moreover, after going through all the trouble of logging in at the right times, at the end you would most often get something like a colour guard; so I stopped trying to do it because I decided it wasn't worth my time.
Oh yeah of course, but it really just promoted activity, and well, yeah, was better early on in a new world as compared to later where all you want is the FP drop.
Getting warriors or more artillery early on was the biggest advantage, but later on much less effective. Another reason to remove it would be the removal of pvp until the end of iron age as having lots of troops is needed much less. of course, Daily challenges, albiet much harder, are much more rewarding in the long run... like getting an extremely early Rogue hideout, now that would be incredibly game changing.
