A few things I'd love to see:
- Horse training queue - ESO+ members can queue a stat to level after that one finishes ( So you can maintain 100% up time without stressing too much)
- Crown Crate Drops - Bosses can rarely drop Crown Crates. Rare, but possible. Maybe lesser crates too with just consumables?
- Achievements for continued subscription
- ESO+ Prepayment - Say if you paid for 12 months of ESO+ and you use up all your crowns (I have done this, please dont judge.. I like pets) you can pay for another 'X' Months on top of that.
