I don't know why all of these builds come with little to no armor, but I just can't do it. So I've created all of my builds with max armor, at least in the upper portions of the 'Mech. 1) 2xERLlas (chain) 2) 3xERSlas (nochain) 3) 3SRM6 (nochain) The idea of this build is to give you some long range firepower, and still give you plenty of close range stopping power without overheating every 5 seconds. Sorry LRM20, but you had to go.
Like this build - full armor with long range firepower that melts the armor off and a close range punch. A solid kick in the teeth with an 18 Artemis-pack when they stroll to close. Clan small lasers are totally underrated and you've got a 3 pack which you can run hot with and still fire all day. 5 outa 5 for me!
