Highly populated servers vs. low population servers

[Nici]

I'd prefer sometihng in the middle high pop servers means more lag in open areas, and low pop servers means harder to form in-server groups (though the duty finder somewhat compensates for that issue)

Yes Duty Finder is a big help on low pop servers, although for people doing their relic quests...and trying to form groups for Chimera and Hydra must be a real chore, as DF does not help with those two parts of the quest line.
