Just jumping in, this reminded me of one of the main principals of rotmg, that all players have the same access to the same content - and another principal that the game is fast to pick up and play, and get into content you are trying to access, with friends of all experience ranges (a 3rd initial principal of rotmg). The 4th principal, that everything you can buy for gold is not personally beneficial has already been destroyed, but this also sort of furthers this divide as well from cash and f2p players (not that even this agent event doesn’t do that - I mean, since Kabam there has been content in every update that breaks the 4th principal).
Anyways, I’m also getting off-topic, but I think the method of getting to o3 hampers all of these principals in some form or other.
Maybe there should be an announcement that occurs in the realm that states if a player in the realm holds 1 of the 3 items needed, it is announced to the realm (not disclosing which player necessarily). In this way at least everyone knows, “hey, I need to get 1 of the other items to go, or get someone who has one and get in this realm”. This way, it isn’t excluded to dischord, guild-events, or otherwise… Anyhow, just some further thought on this…
