Need a go-to mech for event weekends? Guranateed bridesmaid status! Make sure you keep those LRMs on separate weapon groups.
Well, LRM20 spreads too much even with +A anyways, you can downgrade it back to another LRM15. You can use those spaces and 1.5 tons saved for anything from LRM ammo to JJ.
Smurfy Repair Team Report: Clerical Error Fixed. Clan designation added to all weapons and engine. No further action required.
You don't need to do cSTD, only cXL. STD seem to be shared, clan or IS. CONFIRMED: BOTH JJ and STD engine are shared. TC are unmarked cause it is clan only. - Checked in game.
As much as I like the concept, I agree that LRM 20 even with +A just seems wasted. Dropping to 3x LRM15+A and an XL lets you have have the same cooling, same ammo, same armor, but be roughly 18% faster and have a two-pack of JJ: Bonus points: still no free tonnage or slots.
