I would class those two as having
weapons that need help, not so much the variants. >.>
Atlas Prime could use a little buff having an LRM10 and SRM4 or 6 rather than x2 LRM5. (start small

)
The Hgauss Thanny really doesn't give you anything more than the Holly gives you other than JJ's and it has a much larger profile, price, and less tons of ammo.
Would like to see some sort of small missile armament on the other arm rather than just a MBL.
The Laserboat Thors are a bit boring, would rather see the return of the Gauss/LPL one.
Would like to see more fighting Ravens.
Is light variants as a whole are pretty rotten and/or boring, which I think is a bad thing given how many people are stuck in lights for a good chunk of the game.
Still not feeling the Loki with the Gauss/Narc, but I guess it is a larger mech with narc.
I'm not a fan of either of the new Atlai, MRMs and PPCs are fine and all, but can I get a ballistic weapon to go along with them? Do i really need 3PPCs on an atlas? Despite the Prime seeming to be a bit underweight (LRM5s and barely any HS), the design philosophy is one I would like to see followed more, yay mixed weapons!
Other than that, we either need more variants or the weapons that are highly featured on some less useful variants should be looked at.
Variants themselves have improved lately.
