The math disagrees with you.
If you are running spellspeed (which you should be if you want the most DPS), you don't get the extra DOT ticks of T2 unless you have a large amount of procs, which you end up refreshing your thunder anyway.
If your mana tick comes early, then skip the B1. Its fairly easy.
A smoother rotation? Thats completely negligible whatsoever. I find the T1/B1 rotation smoother - less cast time, more movement, more dps.
AOE rotation? Again, what content do you have to do an AOE rotation that matters? You certainly don't in 2nd coil or any of the extreme primals.
If you want to keep ignoring facts to try and justify using a useless stat on your novus, then go ahead, but i'll make sure that people know you are talking rubbish
Piety does not matter for a BLM for any meaningful content. Simple.
