It seems to me that this little change would help him significantly. Not sure I've ever dialed in a surge when I wasn't using regenerative magic. Even with regenerative magic, dialing in one surge feels bad.

Having double surge on the dial makes it a potentially viable choice to shoot for regenerating wounds even without regenerative magic.

I would enjoy if FFG released a Waiqar update package with a few reworked cards, dials, and rules concerning Waiqar. However, at this stage, I'll need to see the impact of the new units before passing final judgement on Waiqar lacking on the battlefield.
