The number 1 mistake most metal guitarist make is thinking the song needs to be played super fast otherwise it sounds weak and wussy. It's actually easier for a band to play super fast because most people top out around the same speed and it's relatively easier to cover up slip ups when you're a blur. Practicing intricate parts at a slower tempo is what made them realize that those type of dynamic shifts could really increase the overall 'heaviness' of a tune.

But again, it all boils down to practice (with some sort of static beat to really build up your rhythmic timing).
