Update 7/20/2017: Changed to ER small. Max range: SLas 172 m, MPLas 253 m Efficiency Skill Tree: Click Here! Atlas Armor Skill Tree: Click Here! Groups:  Alpha strike  6 MPLas  6 MPLas (chain-fire) Proof?: link If you were using 6 MLas 2 MPLas before ( The weapons got linked together), with this build you are trading a little bit of range for better heat efficiency (By 4 heat), cooldown and duration (25%!!). Just spam the alpha button as fast as you can if you don't believe me. side note: if you put 25% duration on medium lasers... it just turns into a medium pulse laser. who would've thought.
