This is how we do it also. For those putting dps in the center, they're just making it harder on themselves.
Our guild does it this way too, actually heal/tank/heal/tank with dps channeling every phase as was suggested in another post, and we usually one-shot the encounter with little difficulty.
The bottom line is that there is certainly no consensus
as to the "right" way to do this. Find what works for you, and stick with it. Be prepared to spend plenty of hours working on it though. I have worked with several guilds who give up after 3 or 4 attempts and "let's just do SM". As stated earlier this is the most difficult encounter in all of TFB, and arguably more difficult than any in HM S&V, Styrak presents an extremely tight enrage timer and Thrasher and Titan 6 are tough on the healers, but none present a more difficult set of mechanics where 1 mistake by anyone in the raid very often results in a wipe.
