Good news for everyone - the ArenaNet crew will be working on QoL things to help keep our hands healthy!
Over a year ago, an official forum thread was started concerning changes that could be made to help keep our hands healthy while playing GW2. Suggestions were made for crafting, vendoring, inventory, salvaging, auto-attack, and auto-target changes. The thread recently got bumped, and Colin responded yesterday:
"Just saw this thread get bumped – missed it the first time a year ago – thanks all! Lots of great stuff in here. Some stuff already on our backlog, some new stuff we added after checking this out."
For those of us with hand problems, or those who want to avoid them, this is excellent news! We'll keep you posted on this topic
