No you cannot complete it until you learn the mechanics.

More dps is preferable to more survivability 9x out of ten though.

As others have said it's all about learning spawns and downing things before they can even attack you for the most part. Depending on what class you are this becomes more important. You won't be able to tank even light attacks from most mobs, so downing them right as they spawn is critical.

Also, big question is are you playing a magicka or stamina build?

Easiest class right now is probably magblade with refreshing path and swallow soul. Since you are just going for a first clear don't run force pulse. 5 burning spellweave or juli, and 5 mothers sorrow. 2 valkyn skoria and which mother potent brew. The healing is amazing. Always run double inferno.

Magsorc i'd run 5 mechanical acuity, imperfect asylum and willpower and skoria with witch mothers potent brew.
Or if you want a bit slower passed combat but much less damage run one of the various vma pet builds you can find on youtube. The pets take a lot of the agro from you.

Stam is much harder but still very much possible. On pretty much every stam build run 5 viscous ophidian (make sure to have it active on both bars. Usually run 3 jewelry and 2 body pieces). For the other 5 piece run any of these; (best to worst) briarheart, night mothers gaze, hundings rage, mechanical accuity. Also run velidreth or maybe selenes if you dont have it. Try to always have vigor ticking and roll dodge attacks if your health is low.
