That was kinda the point, GGO has approximately been developed, alpha/beta tested and marketed all in 6-7 months there's bound to have been major updates etc. I find it ridiculous to expect a huge shooter VRMMO with tons of weapons would be balanced at this point or be perfectly balanced roughly 3-4 months later with the development time in consideration. Honestly I'm more surprised people haven't complained about how famous and bug free the game seems to be considering the short development time, that's what I find most unrealistic about this game.
But yes you're right somebody probably tested light sabers, but tested is pretty different from investing the time needed to get good and develop a play style centered around light sabers. I just don't think someone invest that time and develop a style centered around light sabers in the short time it's been out considering how much a light saber costs. It also depends on the business model if it's p2p which I'm guessing it is and only one character per account then you're usually more careful with it. If the game had been out for a year then I'd say it's ridiculous that people hadn't seriously tried to make a melee build yet. Also the majority if not all the people in this game seems to be sheep that follows the trend and nothing else.
I'm curious about the convertion system, what do they do about names? If you convert from ALO to GGO what happens if your name is already taken and what happens to the name in ALO is it free to take? Can you play an easy f2p game and max your stats and then convert to a game like GGO with those stats? What about games that have rebirth systems so you can push your stats even higher, do you keep those stats when converting and end up with a character with max stats in everything? In fact what's keeping people from making some kind of mod like VR world where you get 999999999 in every stat by stomping a flower and then convert to a VRMMO? It's a really nice idea and all but I do not in any way buy that someone hasn't abused it yet.
