2 LRM15 do about 25 points of damage, spread across 8 locations (assuming frontal and no weird "hit the back" stuff). That's 3 points a location.
In comparison by tabletop, 2 LRM15s would result in 18 points of damage, in 4 locations (cluster of 5/5/4/4). So firstly, it's supposed to scratch paint. Secondly, it's working more or less as intended.
LRMs were never designed to be dominant on the TT. It is meant as a sandpaper weapon, to reduce the armour from range so that close-in weaponry can have an easier time. The translation at the moment to MWO does feel about correct.
