Ye I agree with this. While there is no doubt that Sundering Cleaver turns every 2hander in a powerhouse, it should also be considered that A) you need gold, and you need to take risks in order to get the gold - i.e. "play smart" and B) it's only available past a certain point.
Neither getting the gold for the axe nor getting there is really an issue, if you know the way.
Thanks to teleport and sneaking you wouldn't even need to have one single fight and could collect many drawing going there over the first floor. You even can rob the drawing out of the ritual chamber if you like and have enough strenght. Place the 'trading' char at the vendor, and you don't even have to worr about overweight. Just sent them to him directly.
