I have no issues with the newly Forbidden cards.
Newly Limited :
Blue-Eyes Alternative White Dragon - It isn't as powerful with only two Blue-Eyes White Dragon, so I believe Semi-Limited would be fine.
Graceful Charity - There are a lot of cards that get effects when sent to the grave (most notably Shaddolls and Burning Abyss). As such, I believe it should remain Forbidden.
Newly Semi-Limited :
Dandylion - It's too much of a combo-enabler for Synchros and should remain Limited.
The following cards should remain Limited. I don't know why they were moved to Semi-Limited.
Dark Armed Dragon
Red-Eyes Darkness Metal Dragon
Dewloren, Tiger King of the Ice Barriers
Wall of Revealing Light
Substitoad and Mass Driver - I disagree with this due to Frog FTK. Unbanning one of them is fine, but not both. If we do this, I would recommend unbanning Mass Driver and leaving Substitoad Forbidden, though I would prefer leaving them both Forbidden.
The following cards I believe need to stay banned:
Makyura the Destructor
Performage Damage Juggler
Return from the Different Dimension
The remainder of the previously Forbidden cards should be Limited, as they were banned for a reason. Granted, some of these are Semi-Limited or even Unlimted in the OCG, but I feel that a bit of a slower change would be better, especially since most of use are used to the TCG banlist.
Destiny-HERO Disk Commander
Witch of the Black Forest
Change of Heart
Gateway of the Six
My Additions :
All of these are cards that in some way prevent the opponent from playing the game and thus should probably be banned.
Mask of Restrict
Rivalry of Warlords
(I may have missed some.)
Debated Cards :
Dragon Rulers - I would prefer to keep them banned. If we unban them, I would strongly recommend limiting them and banning the baby Rulers, as well as Super Rejuvination and Return From the Different Dimension (which are limited and semi-limited respectively in this list).
Rank-Up-Magic Cipher Ascension - If we go with 4000 Life Points, this should definitely be Forbidden, as Neo Galaxy-Eyes Cipher Dragon would become an OTK. Even under 8000 Life Points, I'm fine with this being Forbidden. Under the latter scenario, it would be annoying to deal with, but still beatable, so I would also be fine with Limited.
