The problem I have with that durability is that it is so durable, more so even than P-47s and F6F-5s in my experience, that it makes it very lopsided against the A6M2s in scenarios. The A6M2 is so fragile and a brief snap shot from the F4F will likely destroy it while the A6M2 has virtually no chance to destroy the F4F with a snap shot and must saddle up for a long, sustained burst of 20mm fire in order to down one. Saddling up on one F4F means another F4F can easily saddle up on you, and his shot is easier due to ballistics of the Type 99 Model 1 compared to the Browning .50.
I don't think the A6M2 should wholesale sweep the F4F from the skies, but I think the domination the F4F has over the A6M2 in AH is accurate either, and that is largely due to the ability of the F4F to ignore the fact it is being hit by 20mm rounds for a little while.
