The length of battles, the pace of combat... and the overall feel of combat.

Then who's to say you won't know how to control your enmity if your a healer/nuker/DDer?

You quickly learn, at least from my past experience, it doesn't take a genius to figure it out.

Generally people who don't care or can't maintain those simple aspects aren't very good at playing games.

That's what I'm getting at. I wouldn't want someone to join my party that has never partied before our PL that class to 50. They won't understand the fundementals of the class and could very possibly mess up the whole fight.

Yea but at the end of the day its a game, I can appreicate if you don't want some random nobody screwing up your primal battle but you don't need to know much to function in a regular party or even a stronghold group.

the thing is, if you make a monster take as long to fight in a party as it currently takes solo, then that means the solo player's EXP drastically drops because they can't kill nearly as fast

This can be solved by earning more XP per kill, although to be honest it woudln't be such a bad thing to curb the XP rate a bit, it way too fast at the moment.
