Grim dawn - Markovian Blitz - Crucible
With the Buffs to Blitz and Markovian set, the good old vanilla deadly momentum Blitz is now a powerhouse. This build used to be an old favorite of mine

I strongly recommend Deadly momentum over Righteous Fervor in Crucible and use the latter only in SR for the extra tankyness. Deadly momentum makes Blitz hit very hard.
Vanguard is also very good for Blitz instead of Storm Beacon Towers
