The reason being, their limited range means much of the time you'll be firing them at beyond their Optimal Range - outside of 180m. In this circumstance, they're just 2 ton Medium Lasers that generate extra heat.
Regular Medium Lasers generate less heat, save tonnage (6 more DHS! Or, hell, remove EndoSteel and take 2 DHS and still have slots to spare), deal full damage to 270 and reach out past 500m. You can make MPulse lasers work in situations where you have few energy slots and a fast mech - not fast as in "Fast for an assault" like the battlemaster, but fast overall. They're just not worth it in this situation, however.
An 6 damage overall, at the cost of 90m/180m range, 6 tons, and 39% more heat per second? No thanks.
IMHO, all battlemaster builds basically start with 6 Medium Lasers. You can then remove one/two ML's in return for LPL's (they're essentially 2 ML's for extra tonnage), or look more into ballistics and such.
That's what ER Medium Lasers are to be used for in the future. Pulse Lasers are better on mechs that can get into range, I agree.
