Have a look in Rank 1 at player setups and replays. Most are using Zark for everything. It has the absolute best all round stats. I’m using it for heat and physical, and my physical can beat almost anything.
My good friend @lordgorgon maxed up an Avenger thinking the same thing. When he realized how crap it was, he fed it to a Zarkares. He is a top physical builder. We are both average top 30 players.
Just advice to save you the pain of making a huge mistake. It’s not easy to myth things in this game, so be careful friend.
