world completion
I think it depends on the amount of new maps. I’m really unsure at the moment if there will be like three or like a dozen new maps.
I can’t imagine they will just add this new world completion to the old one, because there would be
a) too many whining about more work
b) it would cause problems for guys who don’t want to buy the expansion.
Most likely they’ll have some reward for completing a map, and, if the amount of new maps is high enough, maybe a special reward for completing the whole area.
None of the new added zones have had anything needed for world completion. Some things added to old zones (waypoints and pois and vistas) did get merged into those zones’ completions and thus are now part of getting the gold star.
Were I a betting sort, I’d put my money on the new maps not being required. Though if they added them in while simultaneously removing the WvW part, I think the rejoicing would vastly outweigh any sorrow.
