Class Merging? More like, Class FREEDOM!

all i have to say is Godwins Law
"The law is sometimes invoked prescriptively to mark the end of a discussion when a Nazi analogy is made, with the writer who made the analogy being considered to have lost the argument."

According to your link it seems it doesn't apply as it was used as an analogy before any discussion occurred (being the OP) making it a valid one.

It would be fun, but destroy any semblance of pvp balance. Asherons Call basically did this, with a few twists (training vs specialization, player determines where to spend primary stat points), and it was a lot of fun.

This isn't Pokemon: Class type combinations would not be fun in WoW.
