It's my personal bias, but in fiction, I really like the idea of 'villain who is full of shit but can actually beat you in wrestling' especially since there are the stereotypes surrounding nobility (them being armchair leaders unless they are young and plucky) in play in this context, which makes the possibility of Grogar actually being able to pull his own weight in a confrontation waaay more exciting than 'my guards will protect me while I spew bullshit, only that they will proceed to die to this awesome person I am confronting'
Grogar's name sounds like an early-game boss's name, tbh- of some Orc/Troll boss specifically. Also, you know, his son is literally called Gawrgaru. If anything I'm expecting a family legend about the founder rising to the top even with such a silly name, with a family tradition of giving bad names to 'build character'. Afterall, if no one dares make fun of your name, you know you've made it.
I didn't even know this, now I feel super validated in my opinion xD
