They could readjust costs, but my main concern would largely be for things like arena. It already costs a ton of points to get a bow / spear depending on your spec. It would effectively double the cost.
They could cut it in half I suppose but would be curious how they would want to alter the stat weights. I’m not saying it’s impossible, clearly it is since we had it before lol. Just seems like it involves extra work for little gain that they could solve through transmog or something if they really wanted to.
Idk, not something I feel super strongly on either way.
