I need a good BLM spell rotation.. Been gone for a year..

To reiterate, at level 50 its still the same. Something along the lines of f3 f1 spam til your mp is low b3 t1 f3 repeat, using your firestarter and thundercloud procs as they occur. For aoe fights its still f2 spam(mix in flares when you can). It wont change too quickly as you keep leveling. At 52 you get ley lines which allows all the aoes in the world to find you easier... it also boosts your speed for 30 secs(1 min reuse). So while going a little faster gives you a bit more damage, but it doesnt really change your rotation. At 54 the new ability is just a way to force firestarter or thundercloud procs, so still no real change. At 56 you get enochian, which is a flat 5% damage boost. Use when its available. At 58 you get your first new spell, B4 which exists primarily to re-apply enochian and give you more up time on that damage boost. Its only usable when eno and umbral ice are already on, and it doesnt apply or refresh your umbral ice status. So you can start to mix one in after B3's to keep your damage buffed and get used to eno juggling. Again, mostly the same. At 60 you get F4(same conditions as B4 but with astral fire substituted for umbral ice), and thats when you move into the full new rotation mentioned above and on the forums.

Just to correct this - Flare is your main source of AoE damage. It's not "mix in Flare when you can" it's "build your AoE rotation around casting Flare".

To expand, the way you should /always/ do AoE is:

F3 > F2 > F2 > F2 > Flare > Transpose > [wait 1s] > F3 > F2 > F2 > Flare > repeat from Transpose.

If you have Max-Ether and/or Convert ready and you wanna use them, you can do up to 3 Flares back-to-back.
I'll also almost always Swiftcast my second or third Flare in the normal rotation to speed up the damage.
With Enochian, you pop it after your F3 at the start and just let it fall off in AoE situations. This is the same at 50 and 60.
