The only way I could see them making a comeback, is with the maybe 3250 rules changes that are rumored to be in the works. For Example, if FFA, ES and XL fusion engines become the new standard, as in no extra crits. Otherwise the rules prohibiting crits across multiple locations basically limits LAMS performance, to Age of War Levels, though some neat things can be done using improved jump jets, and Clan weapons and equipment, like DHS, ER lasers, and Clan LRM's.
