Guild Wars 2

Has ANet stated how they’ll handle future elite specializations, like 4/5 xpacs down the road? If they add a new elite spec for each profession with each expansion, there’ll be like five or six elite specs per profession. For someone who just buys GW2 and goes into PvP for the first time, they’ll be really, really confused by all of the normal specializations, not to mention the half-dozen elite specs to choose from.
Are they going to implement a system like they did in WvW? If so, will they just do core Tyria (whatever that is by then), or just the expansion area(s)? And if the xpac areas, the most recent xpac, or all xpacs?

The elite spec slot is only the last slot and you can only have one elite spec active at a given time, it’s not that confusing to begin with unlike Gw1, Gw2 expansions are not standalone games so they will have access to content based on what expansion they have.
