I think I gotta agree with Liam Harper here. The grand majority of the game tends to be pretty casual friendly. Outside of EX and Savage, pretty much everything can be beaten by the average player without much stress. And Extreme really isn't that hard with a bit of practice.

So I feel that it's okay for Savage to be hard, and it's okay to have a few rewards locked away behind it. There's nothing wrong with having a few rewards for hardcore players. I don't begrudge the hardcore crafters the stuff they've been getting (titles, mounts, etc) even though I have no plan to do them.
