Where exactly did you decide that they'd be able to get quad-shreks?
.
1 shrek purchaseable, 2 supply drops for an extra two make for a max of two double-shreks....
Not too much worse than double shrek vet 3 storms, tbh - even less fearsome than they are...
110*1.25*1.2*4 = 660 HP. Will only one-shot vetless shermans, anyway.
Where was quad shreks mentioned? Read the thread's posts again, and then Ucky's. The ambush modifier will make a single shrek do greatly increased amounts of damage. Take a look yourself, I'm no master of numbers or how the weapons work but this is what I found:
Fsj Vet 3
Vet2 Accuracy 1.15,
Vet3 Damage 1.2
Kurts Finest
1.1 Accuracy
Crete
1.2 accuracy
1.15 damage
First Strike
1.25 Accuracy
1.25 damage
Accuracy modifier: 1.8975
Damage modifier: 1.725
So a cloaked Fallschirm squad fires a shrek at long range against a sherman with 66% accuracy (short to medium has perfect accuracy with this modifier) and if it penetrates.. the hit deals 181 damage. I think you only get 1 use of supply drop now atm, but if you did get 2 you could put them on the fallschirm squad and more than half health a sherman every time.
I dunno, I expected the numbers to be much more badass, maybe it won't be so bad as supply drops and the difficultiy of your fallschirms facing the right way will severely limit it. What lacks here is the "Relic Beta Ambush" ability which gave 3 x damage and 2 x Accuracy. It was made TBA recently though so it might have been cancelled by the Dev team. With that ability though..
Accuracy modifier: 3.795 (perfect accuracy at any range)
Damage modifier: 5.175 (!)
Two shreks on a FSJ would then insta rape the sherman, barring 5%, each of them dealing 543 damage.
The biggest limiter here is that fallschirms cant turn in cloak without canceling cloak, and the "cone" of their weapon direction is extremely narrow so the shermans or whatever would have to perfectly drive into their angle for this to be successful.
FSJ shreks would probably be good but not overpowered as long as you were unable to pick up tons of shreks on one squad or as long as the Beta Ambush thingie wasn't implemented.
