Treasure Hunter has been a big argument between different people since its inception as Squeal of Fortune. Many have enjoyed it, others have hated it and those that are in between.
For those that didn't enjoy it, there have been only two options to no longer participate: Ironman or OSRS. Not everyone wants to create an Ironman Account just to disable Treasure Hunter. Same can be said about switching to OSRS.
So, I suggest a new option. The ability to disable Treasure Hunter through Character Creation. This would be the same principle as creating an Ironman but without all the locks an Ironman Account has.
Once the account is created, there will be no Treasure Hunter Promotions or Keys available to the player. There will be an option to reactivate Treasure Hunter but with a couple conditions.
First is that once Treasure Hunter is enabled on the character, there is no turning it off again. This would prevent continuous turning off and on of Treasure Hunter.
Second is that any Guaranteed Treasure Hunter Keys (i.e. Completing Quests and Daily Challenges) would not be obtained on enabling. This would be same as when it first started, no Retroactive Keys.
With this character type, it would allow for players to get a new look at RuneScape 3 without changing it completely.
