While this thread started out with a specific question, it seems to have broadened out to a general "sorcs are useless WHY" thread.
To which I say: please master the class before crying out how weak it is.
The preceding comment is fairly telling: if a sorcerer is roughly equal to an
Evoker, then it clearly can't be all that weak...
Regarding Wild Magic:
A Wild Mage Sorcerer has the potential to gain advantage N+1 times each day, where N is the total number of non-cantrip spell castings/slots allowed to the class.
Including slots from Sorc points.
Which is huge, given that
you decide freely when to use it.
- A feeble pit trap opens up beneath your feet. Ok, I'll save my Advantage - I think my high level Sorc can survive a few dice of damage.
- An invisible Liche casts a major save-or-die spell on you. I believe I'll have my advantage on this save right now, thank you very much.
And then you cast
any spell back at the lich, and automatically gain back your advantage...
Pretty heady stuff if you allow me. And I say that despite polymorphing myself into a Sheep just last night...
