Levi doesn't leave town without a pld for chain stunning that's 2.2
T6 even then you want a cover for bees unless you have a really veteran group. And hollow ground for super slug if I remember right in worse case.
And most single tank runs are still with a pld in old coil. A war is amazingly above and beyond for single tank runs for most groups. No one wants that, just go with a pld.
There's just almost never a time you don't want a PLD in end game. Can't say that with a war.
