Yup, this is even after they made them cheaper by buffing the craft from making 1 whet/weightstone to making 4. One small problem: they ignored literally every other issue with it. One of them uses the wrong profession node, they dont use ironclaw at all (which is cheaper than both bismuth and null stones), they inexcusably use a null stone, they even for some reason only buffed it to four instead of five when both historically and with oils it should be five.
The “intended for melee” option shouldnt be 4-5 times the cost of the bis caster options, especially when many melee have to buy 2, and the problem is the null stone. Sure, null stones will lower in price as the expansion goes on. So will almost everything. The whetstones will always be significantly more expensive than oils if they dont change something.
