Good tips but you are right, you certainly are no monk expert.

I haven't levelled mine yet but through looking at the skill list alone I can tell you that TK is a dps increase if used correctly in your rotation.

In a sustained fight with few breaks, the final phase of A4 immediately coming to mind, you can Tornado Kick off gcd before an immediate snap punch. Use pb, again off gcd, then two more snap punches. Gl3 is powerful indeed, but doing this mitigates the majority of the drawback of Tornado Kick, while ensuring your dps actually increased as opposed to not using it. In fact, I would test without pb too, because you will be surprised with the results.

For best effect, time your Tornado Kick to the last 2 seconds of b4b. This will make sure you aren't wasting a powerful buff on those 5< seconds you are without GL3.
