Don't go fury if you're looking for pure dps, it's a bit gimped. (I play fury when the guild isn't doing progressive content, it's just funner imo).
Always do your execute proc before anything else. It can't proc again if it's currently waiting for you to use the current one. The only time I don't use execute as the next skill when it's available is if OP has been procced for 4+ seconds because if you don't use OP within 6 seconds it will just refresh the proc to use it regardless if you've used it or not, so it would be a wasted OP.
