Like I said, the argument that 10/10/5 is too little, too much, or just right, is NOT what I'm arguing. The miscalculation of gold per mats that scene_cachet, and now you, are using is what I am addressing. In that, you are both wrong.
Thanks for providing decent math instead of FUD & hyperbole others are spreading.
I don't think BW is going to lose any sleep that players have to actually save a little materials, or balance amongst their allies to spend for the priviledge of fighting dragons. They've already mentioned the cautionary warning about dragon calling. There's nothing stopping people from enjoying the castle map without summoning dragons. If you personaly decide it isn't worth it, you don't have to do it.
The rest of us that do decide its worth it, will enjoy the benefits of dragon weapons on perilous.
