Thieves in GW2 will get the F2 key to use stolen items instead of F1 with the specializations update.
A heads up: we’re adding an F2 button for the items that you (thieves) steal from enemies.
With the way that stolen items exist, it’s not always the best option to use your stolen item instantly, but often you have to dump it in order to gain access to Steal again. As a quality-of-life change, you’ll now steal from an enemy and see the stolen item in the F2 slot, while F1 will show Steal and its current cooldown. If you steal again without using the stolen item, it will be replaced/overwritten by the new one.
We weren’t able to show this on the core specialization livestream, but wanted to pass the message on so that it’s not just a bomb drop when the core specialization changes happen (when they’re ready).
