Just a few things I can think of that still require gold membership
- Can't setup a trader without Gold membership
- Can't use journeyman mercs without Gold membership
- Can't use prestige gear/augs without Gold membership
- AA's are still capped without a Gold membership (or SC unlocker, not very cost-efficient)
- Spells are limited to Rank 1 without Gold membership (or SC unlocker)
- Cannot Play on Progression servers without Gold membership
- Cannot use ingame email
