They're only useful for cosmetic and extra quests and the like. You can just straight up ignore them and not lose out on anything.

You are right. I'd bought some gems with my Google Opinion Rewards money, and the only use someone has for gems is for costumes and backgrounds - all cosmetic changes, nothing that affects the gameplay. IIRC you can use gems to change your class if you wish, but you get an Orb of Regeneration at Level 100, so you can change your class for free at that point.

Awesome that is exactly what I wanted to hear, thanks
