The Wild Sorcerer is definitely a build whose core engine is DM optional.
Therefore you need to ask your DM before you roll up one.
Unless you get Tides of Chaos on each and every casting on a spell, don't bother with the sub-class. You will only get the disappointing results recounted above.
The problem with the design, then, is:
They failed to make it abundantly clear that the power of the subclass relies on you the DM being maximally generous.
I think that is an over exaggeration. I do agree that it is wise to discuss with your DM any class before building a character. I tend to have a similar nit pick with the UA Ranger BM and DM input with the companion selection.
IMO, a DM that hands out Inspiration will be more likely to refresh ToC. They are essentially the same thing.
