Well you can ask all the people I constantly wreck about my build. I have tried a build like the one you posted but at least in my experience I just ended up just playing elemental because with out the damage bonus to WF and the added weapon damage, your melee hits / crits dont hit hard at all. Without those 2 talents you lose about 300ish WF crit damage. With my build you have full windfury damage + elemental level spell crits.
Sure you dont have stormstrike, but if your stormstrike doesnt proc WF then you just wasted your mana. 20% extra nature damage to an earth shock (assuming you go glass cannon SS spec with atk power / crit) is going to make you ES do like 600 - 700 damage. My earth shocks already do 600 - 650 without stormstrike. Plus what if you need to frost shock or flame shock a rogue, the SS buff gets wasted. If you crit with a shock unless it is with ES and SS it is quite underwhelming since you will probably have no spell power and you end up hitting like a wet noodle or a hurricane.
Also SS is a 20 second cool down, so that is basically one use per fight in 1v1. No WF from it and no ES crit then its just not very useful.
