I have recently been informed that taking Shredder Ammo as a MSGT perk does not work properly with GSGT rapid fire. As in shredder ammo will not be applied by rapid fire if fired from a MEC weapon. Rapid fire and shredder does work properly for assaults with the shredder ammo item and gunners with both perks.
That said, rapid fire + heat is amazing on both Shoguns and Valkyries.
I know some very good Long War players that recommend sapper on Shoguns (otherwise the same build) because it makes the grenade launcher level enormous amounts of cover, like a dangerzone rocket.
Valkyries are weird and can be built lots of different ways and I really don't think anyone should stick to a single build for them, but rather fit it for the campaign. The only obvious build they have is Rapid Reaction -> Opportunist and i've not found that build to be amazing, it in fact doesn't really pop off until very late game when you can stack battle computer + scope on a MSGT valkyrie with officer bonuses. It is intensely unreliable and unimpressive before that, at least based on my own experience attempting it.
Other builds are the target-painter build for when you don't have a shred gunner - platform stability, shedder, sharpshooter, with the holo-targeter item. And with access to heat-rapid fire they can be a very strong mec. I always recommend plat stab for light em up synergy because RTS is a terrible perk.
I never take collateral on valkyries because its a little late for that perk to be super strong and because of ammo issues. But its definitely pickable.
