It's everything your mom told you NOT to do on a mech. The heat efficiency is low (but very manageable with each set of weapons tailored to a different range). It's running an XL on an AWS --- but in a mech that's not designed to be the first guy over the hill. This is the one shooting "that guy". It's the ultimate "how did that much stuff fit into an 80-ton mech" mech. If ammo's a concern, you can save it by chain firing the LRMs (which is kinda what you should do anyways). And you can always downgrade one or both SRM6's to 4's and fill a ton of whichever into it's place.
