But are they allowed to do that? Wild Sorcerer is a DnD class, it belongs to WotC and probably has to obey the rules of DnD to the letter.
Sorry to say, but there is A LOT with DnD that Larian hasn't followed to the letter. Taking the sorcerer for example:
Dragonic ancestry sorcs get an extra spell at lvl 1.
sorcs have access to three metamagic feats by clvl 3(normally they don't get their third until clvl 10)
Quicken allows to cast two leveled spells during the same turn.
Chromatic orb has been changed to create surfaces in several damage types(this affect all arcane casters but it was introduced together with the sorcerer)
And that's just one class.
