Have you ever seen a 4s 9000mah 60c pack ? no
I know for fact that batteries can cause esc failures. We've tested it, and seen it. Even though your batteries are rated "here" they may not be performing "there".
Rx8's with blown caps are likely failed due to poorly performing batteries, period.

I completely agree with all the except for the statement "
Large Mah packs are often 2 "other" packs in one case. All of this adds up to more resistance". Large mAh packs are usually in 2p (or more) arrangement, which would
decrease the resistance by half the amount of a "1p" pack.
But, yes, ESC failures where caps are overworked are definitely caused by the battery being pushed beyond its real-world rating, no matter what the C-rating, mAh capacity, or number of parallel cells. It doesn't necessarily mean the pack quality is poor; it could be a setup issue (geared too high, improper components for the vehicle, etc), or any number of other things.
And FWIW, I don't like 2p packs; more connections to have issues...
