Guild Wars 2

First, this might only be happening to engineers (I asked my party members, and they seemed to have no problem).
I can’t swap out my utility/elite skill after a forced transformation. I first noticed it when you are transformed into a ghost in Ascalon Catacombs. But it also happens in the charr fractal (probably thaumanova too).
Well, I can swap skills, but only once, immediately after transformation, and before entering combat. Once I either swap the skill once, or enter combat, I can no longer swap the skills until the end of the dungeon (when transformation ends).
This is very annoying because I prefer to use different utilities for clearing burrows, then swapping for the boss. This would be a nightmare in Thaumanova, if it happens there too.

No, it’s not an engi-only thing. It happens to all classes in any situation where a forced transformation occurs (charr and thaumanova fractals, AC p3, and any other similar palces).
