True, but don't leave out the skill it takes to work well with a team, cultivate allies, etc. Dwaren was complaining about groups escaping from him, then returning with bigger groups and killing him. He seems to think this is unfair or wrong. I think it makes perfect sense and if you can stop thinking that fighting solo is all that matters, and start thinking about how your going to win the war against magic for example, then you would put work into cultivating allies and learning to fight together. That's what Cabals are in a sense. And I think the rager cabal is well designed for teamwork since the changes. It seems to me these skills are more important than being good at fight solo. I can put time into finding haste and aura potions, or I can put time into helping a like-minded healer gain ranks, or a like-minded necromancer gather his quest items. I prefer the latter and it has its advantages and disadvantages(Ideally I'd have the time for both).

If your outnumbered and can't beat them, cultivate allies.

"So in summary, ganging is fine, but if you need a gang, you are inferior to someone that does not."

True, and if you need a gang, and don't have one, you're inferior to someone who does. And Dwaren, eventhough he was could take small groups, did need allies.
