The problem with going temple first is that your opponent can force a win if they know what they are doing. If hogs attack your base while you try to capture the resource/reactor, you are going to lose more money than if you went warehouse x2 first cause the hogs will keep taking down your buildings. PoR can't stop it because you won't have blessed. Even if you had blessed, you won't catch the hogs anyways. And going temple first guarantees you won't have the $$$ to afford blessed and a turret.

Warehouse x2 with turret is pretty much foolproof......literally. Nothing can go wrong with it. You could even go temple 3rd or 4th safely if you build the 3rd-5th buildings under the cover of the left turret. Since it's impossible to get attacked before building #3, you should build those on the exposed sides first. Another reason to do the slow method is because you will need those turrets later on, even if you don't get attacked early. A few fuel rod turrets and 2 hunters will pretty much stop any gauss hog attack. Shield generator won't.
