Dunno, since is it going to be like the old AP where you could get from 1-180 in a day w/ +8 or better gear, with massive zp drops also the custom leveling maps were a bad place even for new players since high levels would camp there.
When the server first started I believe the XP was x50 & the zp drop was 4k, then after more people started to play the XP was change to x20 and about 1,800 zp might drop.
Make the server one definitive setup, sticking to that plan with small server implementations but never making a mass change without consulting your player base, otherwise probably No.
