I agree, they definitely need to bring back the variants and a GW2-like upgrade system, but with some new alterations. I also really liked the story quest parts of BFN. The big maps were cool (although I wish they had more of a GW map vibe), and I would love it if they gave that another shot in a GW3. GW2 had a lot of potential to build on lore and world building with the gnomes as a common enemy, infinity time and stuff. I also like how they gave more personality to the characters in BFN. I think it would be cool if that was expanded on as well
