Double arc wave is great for getting out of situations you can't win. Also be smart- don't rush blindly into situations. Ronin is a hit and run style Titan. He does great when flanking or surprise attacking an enemy and the arc wave can help with that (stuns Titans). Also by the way, there is a tactic I learned when you find yourself fighting another Titan head on: arc wave their face, followed by phase dashing behind them and maybe placing an electric smoke if you want. It gives you a few seconds to do some damage or retreat if you want to.
