Hey there! If your worry is about being an 'unofficial Aurorlock', then you shouldn't be worried! If you want to roleplay, most of which the students are involved in is unofficial! Official RP is roleplay that is run by the Seer team, and you would need to apply for the position (most of the time) to be involved in the official storyline. However, this doesn't mean that you need the Aurorlock prefix to RP as an Aurorlock! RP is for everyone, no matter what they buy on the store. You can always contact Matt or Rani (Chief and Deputy Aurorlock in official RP) or any other Aurorlocks who are active in unofficial RP if you want to get involved or get help. I know that you can also contact Aarooncia or Alexander, or really anyone who's involved in the current influenced unofficial RP. I'd be happy to get you involved, just let me know!
With the suggestion, I do agree with other people's points. Since these prefixes and packages are purely for cosmetic purposes, it would be unfair for the people who bought them for (very very expensive amounts of money) on the store. Putting into perspective, the Phoenix package costs about $50. This means that, with the recent proportions that PotterworldMC has to offer, players would be rewarded something worth more than 50,000 gold. This is probably the most gold I've seen offered in quests, and if not, way more. The other thing to think about is if you are offering something for 50,000 gold in worth, what if the players don't want the package/prefix? They'd want an alternative, which would result in the quest giving even more rewards than that prior 50,000 gold.
