And yeah, I don't think Staff condones sparring in apartments. I mean, I guess, if you put the RP into it and you don't have any furniture in there, it could be a sparring room. But when it's full of couches and beds and things, sparring is sort of silly. I look at my bedroom and laugh a little thinking about 'sparring in there'. But, like I said, if you have a spare room and you turn it into a sparring chamber...I don't (personally) see a problem with it, but I imagine Staff might.
I'd love to see a mid-level sparring academy sort of place in Zalanthas, but I think it could be tackled with a MMH and someone with a bunch of gusto! I don't think the need is so great that it needs to arbitrarily be plopped into the game.
I do know Akaramu's feel, and I think I struggle to have a 'combat character' in Allanak who doesn't readily join the Byn. I typically go Rinth, just because there's less questions that need to be asked, and while I don't wantonly murder NPCs, I do engage in petty scraps and over time that's good enough to be 'alright'.
