Following @Excalibaard trend name, as well as an attempt to revive the almost dead mauler _ If it works on clanners to avoid ghost heat, why it should not work on a IS mech? Quite hot brawler with huge alpha but no ghost heat issues. Alpha strike to open the poke, keep on hammering with those UAC cannons once you are getting hot (UAC jam quirk should help a lot) Good ammo count, good speed, decent cooling if you rely mostly on ballistic (like you should), laser hardpoints pretty meh.
