I myself always use Rugged. Not needing it would allow me to always use Quickened Discord, which basically leads to Blast Wave and Touch of Palsy being permanent effects on my opponents, as long as I get my rotation right.
Constant damage when an opponent moves along with a permanent -750 to their health, and I get to keep my current toughness?
Yes please!

Hmm, need to look at the dwarf and see if theres anything unbalanced there as well...
