How would your game change if you didn't know how many Achievement Points you have collected?
Irony aside, this is another thing that ZOS ought to address because, as some of us know, there is pretty much no reward system, or if it exists, it is not much encouraging.
Take for instance IA - the idea is FANTASTIC (no, this is not irony) but the rewards do not encourage one to actually grind. Check some forum posts on the class armour.
Colours, you say? As a reward? No, thanks. I'd rather have a permanent, ACTIVE bonus. Say... a percent bonus to gold gain from monsters.
