They are, the difference is only if you get a proc.

[QUOTE=Garotte14;3849046]Just to Echo what a few others have said:
Use if you will not have to move
SC > QS > LL > Fire > Enochian + Raging Strikes > F3P > Potion > Fire IVx2 > Fire(no proc) > Fire IV > SC > Fire IV + Convert > Fire IVx2 > Blizzard III > T1 > Blizzard IV.
SC > QS > LL > Fire > Enochian + Raging Strikes > F3P > Potion > Fire IVx2 > Fire(procs) > Fire IV > F3P + SC > Fire IV + Convert > Fire IVx2 > Blizzard III > Thunder > Blizzard IV.
Wouldn't it be better to move raging strikes forward in the opener a little? so you can snapshot t1 still? I guess all that would be looking at is what is more potent, a RS> 1AF F3P vs. RS> T1
So like http://ffxivrotations.com/8ol
Your fire 3 proc in af1 is more potent than anything except a full duration t1, so you're not only delaying rs by 1 gcd (dps loss in itself), you're lowering the potency of the opener about 40% of the time.
Unless you have enough piety to cast a 5th fire 4 in your second AF3 cycle it adds 0 benefit that I can see (aside from ease of movement)
The main purpose of precasting Ley Lines is very simple. It's one less oGCD that you have to cast during your opener. Saving .5s when all of your buffs are up plus all party buffs like Battle Litany, TA, etc. is so good. I can't stress this enough, your opener is so important for DPS. You want to squeeze every millisecond out of to put you in the best position to sustain a high DPS.
