If you have solid DDs it can work, depending on the mob. Some are simply too weak and can't take more than 1 WS, like the tigers in Vunkerl. Others, you really need all the DDs on the correct mob. It's not a bad idea and I support it, situationally. I think the core thing we need to do is make sure people are using their WS at the top 20% of the mob. (80-100%) Or, we need to target mobs that can't produce Ruby.
