Fast and enough Ammo to deal more than 800 Damage. Also suited for Hit&Run against heavier targets. Blagg
I think that you can get similar speed SHD-2D2, with 4xSSRM2 2xML, sturdier SHD chassis and JJ on top of that. By sturdier, i mean easier to manage damage of course.
I agree with you that the SHD is more flexible with JJs. But hey, the SHD doesn't have Pentastreaks. PENTAstreaks man!!! This is more disturbance. You should compare among the builds within a Chassis/Variant. There are always Mechs which are more versatile due to more versatile hardpoints. That doesn't mean that the builds on the mechs with less hardpoints are less effective.
No need to get all defensive. I was just checking where can i use XL350, whether it's a good investment and came upon both builds - they're quite similar after all. I can understand the differences inlcuding additional screen shake from the 5th launcher. My point is, you get a similar package with JJ on top there. And i think it has something to do with SHD being slightly OP among medium mechs.
