Well, let's necro this thing and give some thoughts. Because I'm like that. Nyah.
Here's the thing. You're 95 tons. You move 3/5- yes, you have jump jets, and that's a huge help in some situations, but still it's safe to say you're not going anywhere in a hurry. Hey, it's an assault Mech, that's not the idea to them, right?
Well, let's review the guns and- oh. In 3067, a brand new, extremely expensive, top-of-the-line assault Mech has one weapon reaching past nine hexes? At SEVEN hexes only three can engage? Granted, the TC means you're hitting more often with that PPC, and the closer you get those pulses get madder and madder, but... man, that's ugly times. In an era where heavies are regularly moving 5/8 and mediums are hitting 7/11, moving 3/5 is acceptable only if you can engage fast targets at range. Otherwise they'll never come near you- why would they? Think of a Falconer- it gives up twenty tons to this monster, but if it stays ten hexes away it can trade the PPC and Gauss for the Sagittaire's single PPC all day long (or until the ammo runs out on the Gauss anyway). And it's fast enough to almost always find a way to stay that needed distance- even if he loses initiative, he can simply back up as far as the Sag can run forward.
Does that make this a BAD Mech? No. No, that close range firepower is legendary for a reason. Not a fan of the rear lasers, particularly when the arms already can flip, but at close range if you catch something there... madness. Shut the PPC off, light up the laser batteries, and your target will melt into a little grey puddle. It's breathtaking- and if your opponent knows what he's doing, he'll do everything in his power to keep it from happening. In that way, using one is like using the old Hunchback- it can't really do much past nine hexes, but no one wants to risk stepping into the bubble- which makes it a great area-denial tool, if nothing else.
As an urban combatant this Mech shines. Jump over low buildings, let loose with your laser spam, if anyone sneaks up behind you can tell them where to stick it with the rear lasers, and if things get hairy you leap away again. Like an Urbanmech times three, if you will- which is fine, if that's what you wanted it to be, but using one in a typical assault role like you would with a Devastator or Atlas is going to result in a really crappy day.
Now, we know the Davvies are building Clan-tech lasers in the Dark Age, which brings up all kinds of fun options of course (Apollo's Law doesn't really apply here- this is WORTH upgrading to Clan pulses). Extending the range of the pulse lasers makes for a machine that is everything munchkin players have wanted for ages- you even lose a couple of tons of weight from the larges, in case you needed some weight back for something. But, being as that's tricked out and boring, I personally would rather not see it happen.
One of the DA novels featured a merc-owned Sagittaire (Wolf Hunters, I think) that had standard lasers in place of the pulses. Sounds like a downgrade, but... lower heat, better range, and the weight of those pulse lasers means there's a LOT of saved tonnage in there for other gear. We've never seen this statted out, but playing around in my head... by replacing the large and medium pulse lasers with standard models you save nine tons (plus I think the computer is removed in addition, if I recall), which means you can do a LOT of fun things here.
As an aside, I've always pondered the idea of a variant that swapped out the ER PPC and Large Pulse lasers on the R for a Trio of Standard PPCs, using the justification that the Chaos of the Jihad fubared logistics and the makers of the design had to make do with the stockpiled weapons on hand.
And then there's this, which I wholeheartedly approve of- like ramming a Black Hawk KU and an Awesome together, then turning it loose on victims. This is beautiful thinking and should immediately be a field refit to every Sag out there, regardless of the situation.
As stock, however, this is an urban warfare machine that has serious drawbacks, making the incredibly powerful and accurate weaponry just not worth the immense cost of owning one. Mod it, or sell it- if you're going to use it, be very careful in how you do so- or your opponent will likely get a chance to salvage it and show you how to use it from the other direction next game...
