Hi there, This build is the LRM boat that i'm using now. For me is highly effective, as i always had problems with light and medium mechs with 85 ton assault only equipped with missiles, if there are at 150m or less you can deal with any mech with those pulse lasers, but you must manage heat wisely. The 4xLRM15 can get you kill shots, and 5 small pulse lasers as defensive weapons allows to fight effectively on second line and deal with light, medium or damaged heavy and assault mechs. Range, missile rack and heat generation skills are highly recommended.
