My fellows irons. THIS is honestly even better than the update we asked for. Is it pricey? Yes, a bit. But mage bandos, range bandos; they are options to lessen the cost. By the time you want to grind out 1k bandos KC, you will have money from shamans and Hydra. Gold is expendable eventually. This price is NOT the hill we should die on. If we keep complaining, support will fall. This is likely our only chance at getting instances, and in a way that legitimately helps all players. This is an instant YES from me, and I hope from you all too.
Glad you agree, GP has very limited use for irons and I don't think it's unreasonable to either ask you to grind some GP before grinding bandos if you want to avoid regular/non instanced bandos, or even grinding for some dupes to dump in the coffer.
It's kind of what the gamemode is all about, gather your resources, then use them.
