I've changed up my 733 build for a more LRM focused design. First run last night in it. Decent component destruction, c-bills, XP. Modules: Adv Seismic, Target Info Gathering, Adv Target Decay. I jumpLRM'd using the canyons while pushing forward and around as we were against a lance of poptarts and multiple Misery/DDCs. Also, you can alpha with not too bad ghost heat if you really want to jumpLRM well as your targets will only last a few seconds.
During the LRM creep I was doing something similar before it was toned down again, I prefer to do without +A however. It is impressive to see the neverending rain of indirect fire. or this one Remember, they were only powerful due to the over-buff on the LRM at the time.
