It actually is a very foolish change. Because of attunements / kits, Ele and Engy were the two professions that didn't have a weapon swap. That made sense. After this change though, they will be the only two professions who cannot swap weapons in combat. Why? Reasons. Anyone new to the game will be asking that question, and if your players end up having to engage in mental gymnastics to reach a conclusion, that is a flaw in the design. But hey, it took them two balance patches to finally listen to the players about Chemical Field / Detection Pulse. My threshold of expectation can't sink any lower. I expect us to be able to swap weapons in combat in about a year or less if people complain about it enough.
