Waystone droprate and buy possebility

Whether a Waystone has a 0% or 90% drop rate listed, the value is fake. I've often had the drop rate set to over 70% and ended up with zero Waystones at the end of the map!

To make matters worse, no new Waystones have been offered by NPCs for over two weeks. And why should I farm level 1 Waystones on normal maps when I need level 10 Waystones to progress?

Please remove or fix this fake value and give me the option to buy Waystones. I work full-time, and when I want to play to relax, I don't want to waste time farming Waystones. Or you could offer them in the store for real money; that would be fine with me too.

the drop rate you're talking about increases the base drop rate by 70%, it doesn't set it to 70%
