Resources trade

Drag0n

It would be really cool if you could introduce a resource trade scheme, I'm finding with a pretty much complete collection(except for pm2, vg, and DuskMourn) that any packs I get via event rewards etc are useless, especially when I have an excessive amount of crafting orbs already, it would be good if we could trade packs we have of completed sets for resources we can actually utilise such as pink jewels or gold crystals, so those of us with more complete collections, or paid VIP aren't punished for size of collection etc.
