I wish I wasn't in a "delete at the drop of a hat" phase. :)
Frickin' relapse*. I've been thinking on it and I know what
makes me delete a character with less than 300 hours. If life
is 'too' easy OR constant beat downs (like being multi-killed
just by different people all day every day)

That being said you might want to determine the 2 month play
time by hours instead of 'months' Bob might keep a character
for 2 months but only log in for 2 hours a week, where Joe
logs in for 8 hours a day. (and Bajula 'can' run a character
out of con in 2 months. hehe)

*I was glancing over the shoulder of a guy I got hokked on
playing and was like "Dude you should flee" (It was pk so it
was already too late) and was itching to take over even though
I couldn't do anything for him.
