Surfaces aside every time I watch Swen Vincke playing his own titles I can't help but being annoyed about how gleefully he does whatever in his power to leverage exploits, cheese their own broken mechanics to the best of his capabilities, etc, etc.
It's not an exception in his playstyle, it's what he constantly focuses on, to the point that even a lot of users on their forums are starting to call him out.
For example the fact that the keeps leveraging the trick of keeping party members out of combat in stealth and then use them to break the initiative queue at convenience.
A serious developer would say "Well, this is silly, we need to do something to limit this" (and it wouldn't even take much work to address it, frankly). Conversely Swen Vincke boasts about it; he giggles while showing his own broken mess on an official streaming and puffing his chest.
