Guild Wars 2

like the title says, Wouldn’t it be better if Karma were account bound like gems, for example people who want God Temple Armor from Orr won’t have to do events over and over again if they already had a plethora of Karma from doing events on other characters?

I’d support this, just for the convenience. It’s not a huge problem for me personally since I only get obsidian shards with my karma (which are account bound), but if I wanted the armor I can understand it’s frustrating if one characters filled with karma and the one you want the armor for isn’t.

Are there any game-breaking elements that would happen if it was account bound?

Jugs of Karma are account bound

yup, Jugs of karma! Just complete your dailies.
