The problem often time with PC villians is that Eventually they have to get caught.
This poses a problem most of the time for one party or another, because either A) the villian has to get caught, put away, executed, whatever. B) He has to escape prison...alot...which begins to make the court system in teh game seem really fail, and in turn anyone wanting to play a guard/patrol type of chr seem the same C) Villian eventually has to die/kill of che, or suddenly see the light ans start skipping through daisies, after they just tried to bring the Lunatic Pandora down on your local tavern last week.
If the constant escape/never caught things happens, players eventually get worn down on the character in question. One can only be harassed with the same plot, same villian for so long without just going to autopilot/ignore mode around them.
Not to bash any ideas, these are just things to consider, because I've seen it happen many a time on Aion.
Everyone wants to be the Sephiroth of the story...but just remember guys...Spehiroth goes away in the end of the story~!
