Is it National Dead horse Week or something?
First the "Gay" question, now this.
I will make my standard response.
PLing yourself is ok if you take the trouble to work skills etc.
PLing strangers is a bad, bad idea. You are very likely creating an ignorant arrogant player who will embarrass you in the future.
PLing a friend who has "just started EQ" is a bad idea. They end up at 50 with no idea about the game and thinking everyone else is stupid for taking so long to level.
Just sit in Paludal and listen to the PLed shouting "Ding" every few minutes and basking in the "Grats". They have no idea and their names are worth noting to avoid later.
If you are going to PL don't do it on mainline exp camps. Go to out of the way places. Mainline loot camps are different - you probably both need cash
Anyone asking in /ooc or auctioning for PL is going straight onto the "dangerous idiot" list. This may be unfair but if they don't have friends then why should I turn them into a higher level nuisance.
And some classes are very unwise to PL. Enchanters really need to learn about mezzing, stunning and CC before they get one-rounded by PoP mobs. LDoN is great for this. The trouble is that many people PL up an enchanter for tradeskills or buffs and then at some point think it would be fun to play them.
The skills argument is pretty poor btw. if you PL a melee with healing they actually do more fighting than in a normal exp group. There is no problem at all keeping combat skills maxed. And casting skills always need practise, PLed or not.
Of course if you PL with memblurred one-hit-from-dead mobs then skills will not increase. I wouldn't suggest this technique.
