When you enter or leave underwater, you have an entirely separate set of skills that automatically populates.
I’d like to see this also happen similarly for entering WvW, PvP, and PvE.
Ideally this would include trait swapping along with skill swapping. The first time you enter WvW it should send a chat message reminding you to update your traits. This should happen when you enter water and have any skills unslotted, as well. I know it took me a while before I realized you could use ANY utility skills underwater. I just assumed they couldn’t be used because my skills got ‘grayed out’, in my mind.
There are ‘default’ settings I like to use in each of these gameplay modes (depending on which character I’m playing as well), and they often don’t overlap much. It’s pretty annoying to feel a need to reset traits each time I want to go to WvW, especially. Sometimes I just want to play WvW for 10-20 minutes, and it’s time consuming and fun-impeding to not be able to switch modes quickly.
Ultimately I end up frequently playing WvW or PvE with ‘wrong’ traits, which seems silly.
