The mana base isn't really that bad, especially considering the lack of Boros and Gruul duals. Farseek does its job and while annoying, so do mana dorks. The mana will only get better come GTC.
I think the slight mana issues are worth it, since in my testing it really doesn't have a bad matchup against anything being played right now. The deck just has so much value its sickening, and can have surprisingly quick starts similar to the


Aggro lists. I have not been disappointed in it thus far, outside of a few games where the mana was an issue (which often has more to do with me making bad keeps than the mana base, what can I say, I get greedy).
