Range Support... The cluster from the fully functional LRM20 tubes is nice as it really shows on impact to the enemy armor.
I considered this build, too. But i really want that second Dakka! Ok, just started my very first game with the Resistance Pack. So i chose this Mech and thius build. And i can say, even though my team was one man down, this build rocked in Team Brawls! Tipp: Use your teammates as meatshields. haha
I was running a lower powered version of this with a standard 320, AC-10 and LRM-10, but in Blagg we trust. Switching over to this build.
