Game Mechanics: Proc Rates

This from the febuary 21, 2001 patch notes....

*NPC AI - Hate*

We've made a number of changes to NPC AI, specifically to the section
dealing with target-selection, or what's commonly referred to as
"Hate". It is not so much that NPCs react differently to hate now than
before, but that we've changed the way that hate is awarded.

--- We reduced the amount of hate that can be caused by a proc. Due to
the high proc rates at upper levels, the amount of hate generated from
procs, and the spells that were selected for those procs, made keeping
the attention of the creature much too easy a task for the tank.
Simply, it nearly eliminated the challenge of keeping a foes attention
at levels above 50.

Not much hard info there, but its possible that the hate generated by procs on p99 is less than on live at the kunark era
