The 200% petxp being left on is very much appreciated.
However, with "time restraints" being an issue with getting this
accomplished, and even being an issue with adding the extra wafes during Creature Carnivals, how about a different approach?
Just leave 200% petxp on 24/7, and add some permanent groups of statues in different areas that are easily accessible for lower levels on all subservers. Placing groups of them outside Randol, Dratan, and Merac wouldn't hurt anything. And the petxp tables are a complete mess, especially over level 60. So, having 200% petxp on full time also wouldn't hurt anything.
It's clear that we're not going to get Carnival events like we desire. Time restraints certainly shouldn't be an issue with this approach.
