I know this could be considered necro’ing an old post, but I’m gonna reply anyway :p
First of all, I love this idea.
Imagine the next expansion pack being an underwater expansion, where the underwater combat gets reworked, the underwater dragon (referred to as ‘Bubbles’ or ‘Steve’) gets revealed and you can play as one of the Largos. That’d be so coool
Now see, I think the idea for Largos as a playable race is excellent, seeing as their models allow for the same armor as Sylvari and Humans, making little to no changes to it.
Also, many of the arguments made against Largos could also possibly be made against other of the currently avaible races such as Charr or Sylvari.
Rapier’s is just too kitten awesome, to be left out!
