It turns out that Ele Blast is Ele's only nuke damage now. I wonder when will they turn the spell into baseline for ele. Some people (if not most) has been asking it for a long time. And yea, it's very likely we're heading toward to LB spamming rotation.
And seeing how ES lost it nuke damage and FS has cd, it's maybe a good idea to turn LvB into our nuke spender instead of ms regenerator. Lava Surge effect can be added with "not spend ms". And maybe also change FS dot regen ms as baseline, while having FE effect to enhance the regen more.
