This build has worked exceptionally well for me. The addition of the TAG makes LRMboats very happy to see me.
I thought I'd add this pic to show you what this mech is capable of: The trick is to hit and run; let the meatshield brawlers distract the enemy mechs, pick the mechs apart with precision alphas and fade into the background before they work out what hit them. Rinse and repeat. Edit: I try to disable heavily damaged mechs and not kill-steal.
