Ele2 is okayish, but Ele3 is a huge power spike due to Frost Cloud.
Linkers and Eles don’t really get along very well actualy. After the Link nerfs, true AoE damage doesn’t get much of a bonus against linked targets.
Instead of FF you could top off with WL. I’m sure @moises_andre12 can vouch for the Linker+WL synergy better than me.
