Guild Wars 2

Engineer
Disabled the “stowing” auto-attack to prevent players from getting stuck holding these kits: Bomb Kit, Elixir Gun, Flamethrower, Grenade Kit, Med Kit, and Tool Kit.

I thought this meant they fixed the auto attack on the kits.. but it is still not staying on auto attack.

No, you can set the equipping of a kit to auto-attack. Which means the second you unequip it, you reequip it. So you’re stuck on that kit until you get the chance to remove the skill from your lineup.
That’s what they fixed.
