I mentioned this on the forums but also wanted to mention it here:

We've never really tied a promo into an event like this, and we normally don't post info like this, but know that this month's promo is easily the most rewarding for credit purchasers that we've ever run.

If all you do is just trade in the Talisman pieces you get, it's already on par with the best promos we've ever run. If you complete the Talismans and trade them in for 2/3 credit or keep them because you want them, it's far and away the best value we've ever had in a promo. Players are also paying for Talisman pieces, in credits, which is another option for cashing out your Talisman pieces.

So if you've been wondering whether you should buy credits, I'd suggest this month is an excellent month to do it.
