Speak with detailed charts, not just plain theories from 2009 based on spell descriptions, math and zero testing here. I don't care about the overall damage output, because it's rng and not a factor - one can crit/hit, the other not. What I care about is the amount used abilities (all, not only successfully landed) and then we will summ the difference
If what you're doing is - Rend on start because why the **** no instead stacking Sunders with the others ASAP - that's wrong as well and is happening often. The sooner your target is vulnerable (Sunder/Expose/Acid + Faerie/Sting/CoW) the faster you AND YOUR RAID will be able to start landing higher/more valuable blows
