I'd rather just get more places to collect it and have it drop from fossil island wyverns (if they're in the game) since they should drop a decent bit of it noted.
(The way you explained this thread confuses me, as I'm not sure what you're going after here)
I'm going to assume you want a new game mode for skillers?
Figuring out how to implement this is pretty crucial
I could see it being added as a custom game mode, but would we include current skillers? If so how would this be done? What if an account reset all combats and then pretended to be a skiller after having such an unfair advantage?
They could have inferno cape etc, which would look a bit ridic
Lastly, the experience rates on alora and the ability to just buy supplies can make the game mode pretty easy, and there's not too much of a sense of accomplishment imo.
I think the challenge aspect of this type of account would be bank building rather than just levelling up the skills. Also, while OP seems to want to be able to convert existing accounts to this mode for a fee I think the only "fair" way to do it would be to require a new account for it.
That said I think my support depends greatly on the amount of dev time this would take. It would be a cool unique option that a lot of servers don't have, but reallistically I don't think it's worth much dev time. Basically if this would take more than a day to get done then I don't support it, but if the game mode can be made in a day then I fully support it.
