I respect what you are saying but this point is somewhat debatable for a fresh Inferno DH.
High DPS/Survivability really only comes in to play with T15/16 gear found in Act 3/4 or on the AH for a bunch of gold. Until you can deck yourself out in this gear, most would advise to simply go full glass cannon.
However, until then, it's a little counter productive because the fights will last longer which means the odds of making a mistake such as catching yourself with no Discipline, Vaulting in to another pack of mobs, or getting hit by Mortar are a higher likelihood than having twice the DPS and half the combat-time. Getting hit by 2k or 30k overkill won't matter so it's best to kill them before they kill you.
That's my opinion anyway.
