Hard finding an enhancement shaman that's actually good but I know where you're coming from. What you said is the reason I'm going Rdruid/Warrior again anyway. Intervene for eating traps is sick. + rdruid/warr has a strong, quite long CC chain but still, nothing compared to the Disc/Hunter CC chain and the fact that you can CC somebody the whole game if their partner doesn't stop you. (literally the whole game).
