GC Twitter: Old Unleashed Lightning glyph benefit is baked in for Elemental. Cast time penalty just goes away. (Anything can change before 5.3 launch.)
Thats a decent single target upgrade (not huge, but still noticeable). Huge survivability upgrade with the new glyph giving 10% damage reduction always on. Sucks for enhance that liked to use the glyph for pvp and even casting LBs with low maelstrom stacks while moving when things were on CD.
