What would be the ramifications of allowing a Wild Magic Sorcerer’s Bend Luck ability to scale with level?

I was wondering why a Wild Magic Sorcerer’s Bend Luck ability is always 2 sorcery points and a reaction to increase or reduce another creature’s attack roll, ability check or saving throw by 1d4.

I think it’s pretty wild (pun intended) that is does not scale with levels considering there’s another spellcaster class, Bards, that have a very similar ability with Bardic Inspiration.

Bardic Inspiration affects the same types of rolls (attack rolls, ability checks and saving throws), does not use a reaction (uses a bonus action instead) and players can hold onto their bardic inspiration for a moment of their choosing. Furthermore, Bardic Inspirations are their own unique resource (equal to Charisma modifier, minimum of 1) and best of all they scale with levels (starting as d6’s and ending as d12’s at level 15). After reaching 5th level, Font of Inspiration allows Bards to regain all their Bardic Inspirations after a short rest.

In comparison, Bend Luck is pretty pitiful.

  1. It costs 2 sorcery points (equivalent of a level 1 spell slot and also the resource required for using metamagic, basically the best part of being a Sorcerer).
  2. It is always a flat 1d4. The chance of a 1d4 being impactful diminishes as you level up & enemies get stronger.
  3. It uses your reaction, which can be super valuable for casting Shield, Counterspell, Featherfall etc.

The only real benefit I can see is that it can be used offensively, whereas Bardic Inspiration cannot.

My questions:

  1. Am I missing something? Have I accurately portrayed the usefulness of Bend Luck?
  2. If I’m not missing anything, is it reasonable to have Bend Luck scale with levels? (At 6th level, it becomes a 1d6, 11th level 1d8, 16th level 1d10, for example?)
