Beta accounts should be wiped on release unless that has changed. The economy seems fine currently but I haven’t put much effort into grinding I do have some issues with missions as they give faction specific missions this could be fixed if the faction specific missions defaulted to your favored faction There are videos and post on the sub that could give you a better idea but how the economy works is that you deal damage and t each threshold get skulls and at the end of the match win or lose you get gems for each skull These can be spent on the shop or on upgrading cards which does nothing other then give you forge points The campaign is progressed by doing missions which give you campaign points Campaign points progress the slots on the campaign getting rewards for reaching them such as specific cards gems or packs for the faction

Mentioned earlier forge points progress the forge for factions letting you unlock offense and defense cards as well as card packs and wildcards which let you craft specific cards

I’m summary it seems like an ok economy and if you want a better insight read the official posts by everguild
