Hi ANet, just wanted to voice my opinion that I think SAB upgrades (shovel, nun-chucks, etc) should be made account-wide.
I was a noob to SAB (hadn't played it before this year) and wandered in on my bulky Charr warrior. I'm now reluctant to play this jump puzzle-heavy mode on anything but my Charr simply because he's the first character I happened to buy the upgrades for.
Please consider making these upgrades character-independent! Thank you.
