Ele Sham Macros and sey up?

[zenga]

So I tried following Icy Veins elemental rotation and I guess I did something wrong.
Used a priority system sending 1-4.
1 Elemental Blast
2. /castsequence reset=target/25 Flame Shock
3. Lava Burst

Lava Burst should have a higher priority than elemental blast, it's something that icy vein has wrong.
