Tasha Preview, Wild Magic Barbarian and Genie Warlock

[Asisreo1]

The worst part of Wild Magic Sorcerer (which is also removed for this Barbarian) is the DM controlled aspect. It makes more work for your DM, you'll probably have to pester your DM about Wild Magic Surges because you have literally no control over when you make one. Our Wild Magic Sorcerer is very lucky that our DM enjoys that kind of macro activity.

The easiest thing a DM can do is give the power back to the player. That is, let the player decide when they want to use the Wild Magic table.

If the DM wants some form of control still, he can veto the Wild Magic so a sorcerer still can't quite predict it but the burden of it activating no longer falls onto the DM. It's something I've been tinkering with as a DM and it's been fun so far.
