Increased is probably from all the increased in marches when they fill flats, but it really comes down to different major issues, such as bots which you see in almost every mmorg and are gonna be hard to overcome especially on a browser based game. The other big issue with flat fillers is the long march cooldown on adv, as well as significant price increase. Items need to be adjusted as a server ages, as in the beginning 90 cents 24 hour cooldown is actually pretty reasonable, but after the server ages the cooldown and price should be tweaked a little (price not much maybe 2x what a tele would be instead of 3x). Same is true for many other items that become worthless with age, reducing spending on aged servers as well.
