Hit it! ^^

Yeah, that's a bloated waste of 45.6 million C-bills.

Without MASC or TSM there's no way in hell that Mace is ever going to come into play unless you run into an Annihilator or another Super Heavy, which are practically non-existent. Not to mention a 160t mech's Punch alone would be enough to decapitate any other mech including another Super Heavy, assuming a lack of Hardened armor. So 16t of useless mass.

Putting artillery on a mech is almost always a bad idea, first off because it's far easier to put it onto a vehicle, not to mention without guided shells/missiles it'll rarely ever hit non-buildings, then the massive penalties to direct fire which is anything within 16 hexes. Then on top of all that it's on the shielded side meaning you need to deactivate the Shield to fire it, and there's no mention of CASE for the one weapon that has explosive ammo, let alone CASE II.

Then of course XLs engines, even if they are Clan spec are a very quick way to get disabled in something as slow as this monstrosity. But to add insult to injury, there's no use of Endo or Ferro, when you have more than enough critical space on a Super Heavy to do so, and for far cheaper. The engine alone accounts for 35.5 million C-bills of the design's cost, especially when it's only saving you 11t, Endo alone would save you 16t.

If nothing else I would change out that overpriced XL engine for Endo, you save 25.2 million C-bills, then add some CASE II to each torso, this protects you from Arrow ammo explosion destroying your mech out right and reduces Gauss Rifle explosion to 1 damage to your structure, albeit at the expense of your rear armor on that torso. That then leaves you with 4t free, you could even go with Heavy Ferro and save another 6t.

I don't spell out every spec in these descriptions. It is already using Clan Endo-Steel.

Good to know, it hurts my little mech-tech soul when people grab XL before Endo.
