Skill in EQ was a weird thing since what that really means depended so much on what your role was. The "real" skill in eq was management, and if you were involved in guild leadership at pretty much any level, you were playing an entirely different game than most people. Your game wasn't auto-attack and doritos. It was recruitment, managing drama, keeping people happy, getting the most out of the people that you had, etc. And really, even though we're all "lol auto-attack", just consider what % of your server's population couldn't even do that right. It's easy enough to say that all you needed was focus and situational awareness, but how many people on your server would you have been comfortable taking along on a really difficult single-group dungeon crawl?
Most of my time ended up being on FV, and with the strange mix of role-players and the plat buyers/sellers (due to the lack of no-drop), it made for a very drama-filled existence. I'm not sure how it was in other places, but since FV had very small number of power-gamers, there were typically only a few guilds trying to raid seriously, and they all had to compete pretty hardcore for the few useful players. It got pretty meta at times with guild leaders/officers hacking rivals forums to stir up drama, secretly buying characters in other guilds just to spy or play (badly) in raids, or just outright buying out key members to hurt their raid capacity or morale.
Oh and if you wanted more to your game that just auto-attacking, charm groups were the best! The things a naked chanter could do with the proper support were amazing. Barring that, you could also keep adding boxes until it got hard to manage. Multiboxing clerics was were a staple of low-manpower raids everywhere I imagine. I know I ran our entire CH chain a few times.
