Hello,
While checking top elemental shaman (from top guilds obv.) i realized that all of them are over 8.5k haste while wearing the legedary metagem. It is clear that with the increased cast time of LB we end up without having 0.8 s casts (under GCD) during Heroism. I just got my metagem and realized that with 6k haste (armory) i already get Lightning bolts of 1 sec. when gem procs . With 8-9k haste im sure that with gem proc i will be under GCD even with Lightningbolt. Why forge haste then? why not go mastery ? or crit?
