On the Dungeons & Raids Page it says you can gain an amount of gold depending on your success.

A: Is gold the only currency ingame? Or will we have silver, platin....as well?

B: Will it actually be possible to complete tons of PvE Dungeons & Raids, thereby collecting lots of gold, which then can be used to buy boosters and cards from the Auction House? Which means people could avoid to have to spend real money everytime they want to increase their collection, since thats something many people dislike?!

C: Is ingame currency only usable in trades / auction house? I guess we will see some form for official shop, where you can buy boosters for $2 etc. Will there be a gold-price for those as well or is gold limited to player transactions?

Thanks again
