Guide
Currently, Totemic Ward is his meta talent.
You could pick Maelstrom in situations where a) the enemy has little to no shields and b) enemy has deployables to bounce off of or are likely to stack together. But otherwise, in 1v1's his shock pulse actually lowers his single-target dps compared to just using your primary fire alone.
