Arcane thievery cast time
Agree that it is a bit longer and extremely difficult to land compared to other abilities. This is probably because ArenaNet perceives it’s a very powerful boon removal skill or because they think it’s more powerful than it is. My personal opinion is they think the latter. Mesmer can rip off 3 boons immediately, plus each clone can rip off another boon if traited, and the mesmer could run null field in addition or illusionary disenchanter. Unfortunately if anyone else has actually used a build with all this boon removal utility (I have), you suck because you lack the ability to actually use these skills due to dying to other things.
