Since there has been almost no information on implementation of this mode I will just post the community “assumptions”
No trading/mail/AH until level 60
Will use existing HC servers
A few issues I have with these things. The main advantage of SF is it is theoretically a bot free server. With no way to trade there is no way for a gold seller to sell gold and thus no reason to bot farm on that server. However by removing this restriction at 60 or using the existing HC servers doesn’t solve this issue at all.
What I would like to see instead
No trading/AH EVER not even at 60
Mail at 60 but only to other 60’s on your account
Add TBC enchanting vellums so you can trade enchants between your own characters
Add new servers that are only SF mode and not intermingled with regular HC servers.
If they are implementing this option for play on the existing servers, there should be no distinction by level. Someone chooses to activate that option, there is no AH/mail/trading at all ever.
You can “turn off” the option but can never reactivate it on that character. Simple. Easy. Direct to the point of self found. No takebacks, reserves or carve outs.
They could make the server like the current HC servers where you can freely move to a non-HC server, but not back.
So you could freely move from Self Found server to non-SF server, but never back.
Main reason I added #3 is to prevent only one character on your account being able to raid. Essentially your enchanter would be the only character that could have enchantments.
So every raid character would be Engineering/Enchanting. With Vellums you could at least mail enchants to yourself.
