there is no way decreasing piercing resistance 10% would equate anywhere near a 10% dps increase. Lets assume the armor blocks half your damage, at 10% decrease you would effectively only gain 5%. That is unreal that people would argue that it's actually a 10% increase.

as far as ct and phleb ending at the same time, it doesn't. in fact frequently I have 2-3s left on chaos thrust when it comes up in rotation to refresh it. I could cast some useless one off skill with low damage and not get the disembowel buff on disembowel cast but that just isn't helpful.

How exactly am I missing out on 2 ticks of chaos thrust for 1 2.5 sec cast delay? they tick every 3 seconds...that's less than 1 tick.

So far I have heard no logical reasoning against anything I have said...
