Hello, all. I've been away from the game for a while, so this is my coming-back 'mech. This is a re-work of the Black-Dragon posted on this forum. It solves the ammo problems that arose from the 12v12 update and adds more close-quarters punch. Chain fire the AC/5's and MLas's to conserve heat.
You don't need any kind of heat management with this mech: AC/5 is one of the coolest weapon of the game, and you won't overheat with only 2 medium lasers and a SRM6. Actually, even the 10 required DHS would be way heat-efficient. I suggest you drop the two additional DHS to add anything you want: AMS, ammo, larger engine,...
As per epikt's suggestions, I removed the heat sinks. I added AMS and armor in their place and haven't noticed a negative affect on my dps. Revision is linked below. Thanks!
