That's a very silly analogy with a gaping flaw: it's nothing to do with what class you play, it's to do with what build you run. I think the one positive to come from the bloodstained insignia is that some people will think "wow, that's too expensive, maybe I should try a non-MM necro"I'm pretty sure that this crafter would be poorly received. Because the whole concept of "similar pricing no matter what class you play or what chapter you're in" is pretty prevalent in the game.
This has nothing to do with runes or dyes or anything else. Everyone pays the same amount of gold for rune or dyes or anything else... except armor. Runes and dyes and anything other than armor? Those are fair for all characters -- because everyone pays the same amount for them.
Armor is not fairly priced, because not everyone pays the same amount for it.
If you really want to be a MM and you really want faster corpse casting, you pay some for it. Same with fire eles: sup. fire runes are quite a lot now because of all the SF heroes around.
