Any chance, want, or need for a battle pack release with errata cards?

I don't think there's much demand for this, and therefore no chance of it being made. It would be nice to have corrected versions of the card, but I doubt many people would be willing to buy cards they already again just for that.

Plus, as far as I'm aware, many if not all of the non-english versions of the game introduced their own errors due to sloppy translations, so they'd need even more / bigger errata packs, while all the while almost every new pack comes with one or more cards that eventually require an errata for some reason ... it'd never stop.

I think it would be nice if FFG add errated old card or two at a time into new battle packs, as they show up. It would be very appreciated by players and I don't think the cost of such action would be very high.

Plus, it won't mess much with company's income, like it would in the case of "missing copies" pack (as right now some people buy a three core sets, so edition with "missing 2nd and 3rd copies" would effectively kill some profit; nevertheless I think it should be done anyway, just because customers' loyality and company reputation gained by it is worth far more than these few bucks in the long term. However, that's a different topic. :))

 Errata packs should be a separate line, and I'd buy them.
