My premise is that the artists and modelers alone anticipate of OSRS gold this acceptable artful of brand and absorber while designing armour sets such as these, potentially afterwards knowledge/thought used to the truth that shields are hardly acclimated in absolute gameplay.
Their tasks are to actualize an intensive set of accessories to enter the game, and that doesn't decidedly crave alive and/or designing about gameplay mechanics (in this case, all-around the incidence of dual-wield aural accessories sets).
Ideally, yeah, they should in actuality accept by today that one-handed weapons are basically always dual-wielded, and that they ought to actualize off-hand models to plank that buy RS gold (with the easiest means accepting to reuse the aforementioned archetypal for your off-hand, or - what I would embrace to see - architecture adulatory off-hands audible in the main-hands).
I accept how it can get neglected, though, together with all the art team's antecedence accepting beheld architecture over appliance aural the match.
As anyone who works within an artistic acreage as an Art Director, if that is in reality the anticipation action that goes abaft the structure of new pieces of gear, it's in reality and horribly flawed.
