For the opener, why not add T3 into the mix? So, in essence:
Code:
240 B3
0.5 Swiftcast
2.36 390 T3
Quelling
Ley Lines
Sharpcast
2.01 168 F3
Enochian
2.01 304.2 F1
0.5 Raging
1 Pot
2.41 635.0 F4
2.41 635.0 F4
2.41 635.0 F4
2.01 544.3 FS Convert
2.41 635.0 F4
2.41 635.0 F4
2.41 635.0 F4
2.01 176.4 B3
2.01 745.5 TC
2.41 294 B4
I'm using the same spell speed as your guide. Other variations include T1 after the 2nd B3.
I realize that this opener is extremely luck dependent and failing to get a Thundercloud proc will result in a dps loss.
