I'm writing this from the point of a PvE player who gets intense anxiety from just stepping foot in PvP environments. So knowing what I enjoy and what makes me feel absolutely awful, I avoid those game modes... except I need to go into WvW for the Gift of Battle every time I want to make a legendary, which I do want to make because nice long term goals and all that. Now, I know that a lot of arguments against just being able to get the Gift of Battle outside of WvW is that the WvW player base still has to deal with a bunch of PvE stuff if they want to make legendaries. While I don't think we can completely remove the PvE components, surely it would be good for both parties if we could exchange one gift for the other?
PvE players who don't want to go into WvW can focus on the slower and probably more tedious Gift of Exploration. And dedicated WvW players can just grab the quicker Gifts of Battle and exchange those for Gift of Exploration so they don't have to spend ages map completing central Tyria.
Yes, I am aware of that one can just do dailies overtime for the WvW track potions, but it's not really about the difficulty, it's the feeling of the game mode. Just stepping foot into WvW has me instantly super anxious because of the risk of getting destroyed by a roamer when I'm trying to get a monument daily, or seek out a veteran creature, and I don't think I'm the only one who feels this way.
