The thing about "clicking", Lensor, I totally agree with.
The way I go about it is that a build has to be fun to play as well as fairly effective. I don't like gimping myself, but I also don't like to run builds that I don't enjoy playing just because they are more effective.
So for me, minions is a requirement, and I have lots of leeway on how to make that work.
But when I look at other people's builds, I generally think what traits would best serve them (and possibly what skill changes). But I try to keep the same weapons and skills as much as possible because I figure that's what they enjoy. I might discuss weapons if I see that their weapons are not used for their purpose (e.g. mesmer scepter for dps... not the best choice).
One thing about conditions I noticed is that some bosses (e.g. tree boss in Twilight), as well as many items (barrels, doors, totems), don't show conditions stacked below the health bar. I don't really know what happens to conditions on them. Are conditions converted to damage? Are they completely lost? I have no idea, and frankly, I think that might be an issue worth investigating.
