You need to see clearly that the ErML is made for range but if you want to brawl you do not want ErML, even though it can be used, because the ML should do it a lot better ei. shorter burn, less heat and better recycle.
Well, this one is at least easy.
The current Medium Laser is already terrible for brawl because it burns too long and runs too hot for its natural (unquirked) optimum range: 270 meters. Right now, an IS laser boat with three larges and five mediums with 19 DHS has a similar, actually almost identical, natural heat efficiency as the Clan 'Mechs running around with two large pulse and five mediums with 23-24 DHS. This suggests to me that the current ML's heat profile should be what the isERML has.
Meanwhile, the typical quirked laser heat profile drops heat output by 10%. Taken across the whole IS bread-and-butter build of 3x Large-class and 5x Medium-class lasers, that's a reduction of 4.1 heat. If you dump all of that onto the Medium lasers (which you should, so lighter 'Mechs can be less gimped), that means each standard Medium laser would be dealing roughly 3.2 heat. That's where your standard MedLas heat should be.
Shorter duration needs to be a thing simply because at 270 meters, you are getting rolled up on by SRMs, cSPLs, cERSL, and cSPL. The only reason the isML does as well as it does today is because it is almost an isERML already.
isERML: 5 damage, 4.0 heat, 0.90 seconds duration, cool-down of 3.15 seconds
isML: 5 damage, 3.2 heat, 0.82 seconds duration, cool-down of 2.75 seconds
