Well, the decay has it's pros and cons.
The start entry fee for some items is too high. If you take away the decay, then all the entry fees would have to reviewed quiet often to make them realistic. Can this be done?
For some items which have a good entry fee people do wait for them to get cheaper because they can wait. If the arena had more participants, then this will not be possible. If you wait, then others will enter.
So decay is not a problem if more people play the arena. It only slows the start of some arena's because of lack of interest in the arena.
There are some level ranges for which I can make a quick slap setup which is not so good, and if the price gets really low, then I enter it knowing that my winning chances are really low. But it cost almost nothing to enter, so why not. If there was no decay, then I would not enter, and others do the same. So without decay these tournies would never start.
