As we know the bloodwood tree at Soul Wars is protected by sandstorm, I suggest that we unlock it by putting a limit on how much a player is able to gather from it daily. We could even have it to where sapphire or emerald ranks unlock the tree and as you progress your rank you can collect more daily. Keep in mind we need to abide by rule#18 and not alt farm it, limit to 3 accounts.
Sticking a bloodwood tree in Donor zone would be ideal since you need to be a donor to access it from the start, players gathering for the tree would interact more and frankly I don't visit regular Donor zone enough anymore anyways either other than for urns.
