Ley lines and AoE

Base cast time of Fire II is 3.0 seconds.

Your dps is not the dps of one GCD. If you could spam F2 endlessly then your numbers would be more valid, but MP limits that. Also, Thunder is more than just Thunder, it's also Thundercloud procs.

It's around 5 mobs where Thundercloud casting falls behind, but of course getting that many mobs together often involves a long pull, during which time you can get a few Thunders in early thanks to Sprint and Sharpcast.

Yeah I would agree past five mobs thunder cloud procs wouldn't be optimal but however by the time you get to the sixth target that first one will be nearing death of not dead anyways so I keep up with my thunder applying.

I don't even like it when SCH's use Selene when I'm on my BLM in a dungeon, as the 3% casting speed is enough to make me finish my Fire III cast too quickly, before the second MP tick, sometimes. That gets rather annoying, as it's not consistent. x.x

Ley Lines and The Arrow only make it worse.
