They are probably looking at it in very high haste levels, where energy regeneration smooths out.
I am much more bothered that we have at least 3 dead talents (Mass entanglement, Feral Frenzy and Soul of the Forest) and one incredibly boring talent (Blood Scent) in our talent tree. Also, more changes should be coming before September 4th, as they mentioned (it is when the actual competitive content begins).
From a PvP point of view, we are terrible in the CC department and we have possibly THE worst PvP talent in the game, Enraged maim. A 5 CP / 30 Energy ability that lasts marginally more (5s vs 4s) than Gouge (15s CD, 25 energy) and replaces our stun. Ah did I mentioned that the damage of enraged main is worse than the regular maim?
