Oh, I absolutely agree, Paladin weapons are also particularly egregious for this like you said; the only reason I didn't mention Warrior by name as well is because they also use some weapons that are hammers, which I think is pretty cool. It's easy to tell when it's meant to look like an axe, though. And again, I imagine even if you were to try to cut something relatively soft, it would be more inclined to crush it rather than slice it based on the width. Other than that I don't play DRK; but RDM weapons are incredibly noticeable to me because they're also thin, so if you widen a thin weapon ever so slightly you've basically just made a metal bar.
But almost none of the SAM weapons look like that, so they obviously know how to make a proper edge, but they just... don't. That's why I'm less likely to look at it like "its supposed to be a wand/staff" as the reason they look like that, because it's a pretty inexplicably widespread visual issue. That's why I like the (i think, i cant look now cus maint) Chromite Axe, which is HUGE, but also very thin, so it looks like a very sharp weapon.
And it's not that I'm acting like this about it because I take issue with the practicality of swinging whatever the weapon is, i'm just looking at it from the perspective of someone who sees it that it doesn't look practical or good to me when it's wide like that, so I feel confused as to why they decided to do that to so many of them in the first place and why it hasn't seemed to stop into 6.0 outside of rehashed models either. I can't even think of a reason why, like it wouldn't be more demanding on a PC to make a thinner edge IIRC. Maybe its an art style or something? but then they don't make the samurai weapons fat either; so why is that?
im basically jumping between two points that just dont make sense when you consider the other. i've played the game this long anyway; its just been my opinion that it doesnt look great and no one seems to talk about it lol
