Guild Wars 2

When swapping between any two kits, your primary weapon auto attack will trigger. I personally do not expect my primary weapon skills to be activated when swapping between kits. This could also provide a competitive advantage.

Repro Steps:
1. Have auto attack enabled on any of your primary weapon skills (tested with rifle, pistols, and hammer).
2. Select grenade kit and lob a single grenade at a mob to enter combat mode.
3. Switch to any other kit after your last kit attack completes. This issue will not surface if you queue attacks or swap kits at the start of your last kits attack. Swapping between Grenade and Mortar kit is the easiest way to see the issue.

Observed Behaviour: After kit swap, your primary weapon auto attack will trigger. Hip shot, net shot, overcharged shot, rocket charge, blowtorch, etc.

Other classes do the same. Try a guardian’s “Retreat” skill when in melee range of a target with greatsword on auto-attack. I don’t think it is a bug, just a possible downside to using it.
