So yeh.. is chain lightning no longer viable in your standard ele rotation? In wotlk it was a dps increase to keep it off cd over lb, unless you had an extreme amount of haste or hero/bloodlust or another haste increasing ability was active, but i haven't really been able to find a place that can tell me whether it's still viable on fights where it won't make you go oom to early.
When i read the ele fag sticky i found no mention of this:/
