Lag-free would be nice.. yet hardly what I claimed. The minimal lag I've experienced has hardly prevented me from completing any content I've attempted.. which is why I'm using the term minimal. It also hasn't been a bother for ME in cities.. I may wait 2/3 seconds or so for people to load in packed areas but never really considered that annoying or anything. It USED to be horrible about a year or so ago.. but has definitely improved alot for me since launch.
The three points you made. Well the first one is a personal preference of yours. I've already said I personally prefer to see and talk with people from different cultures in different languages.. The second one doesn't even really makes sense when your talking about comparing to GLOBAL servers. By definition there is greater population density across all timezones represented and therefore more opportunity for a higher average population at any given time of the day. While regional servers foster "primetimes" where the population will swell and die at particular times of the day. Ideally, as long as your life schedule falls somewhat akin to the typical NA timezones represented, you should generally find a high healthy pop, however for those people with 'wierd' schedules.. you'll have to choose between playing on what feels like a dead server, or choosing another region that fits your schedule but may provide a language barrier due to the fact that 90%+ of the people don't speak your language (as opposed to global servers which would ideally have a more equal ratio of popular languages represented). And the third, easier to find groups yeah, most likely. If you play during primetime. Global servers do at times create more reasons to exclude others from grouping, simply because it's a more diverse server, but that shouldn't be used as the excuse... for I'd hope obvious reasons..
