My DM is using this homebrew version of True Strike - too powerful?

Surely the RAW version of the TS does exactly that?

As I'm sure you already know, the trap of true strike is that unless your character benefits from having advantage (Elven Accuracy or Rogue Sneak Attack), then you're better off attacking twice as opposed to using true strike and then attacking the next turn. The only exception to this that I can think of is if a caster is using a high level spell with an attack roll, and they need it to hit.

Therefore, the draw of "fixing" true strike is that it's such a bad spell it's practically begging to be fixed. There are many threads about it, so we don't need to get into it too much here, but the general consensus about homebrewing true strike is either
1) Make it a bonus action, but give it some negative that makes you not spam it every turn (takes concentration)
or
2) Make it a blade cantrip that has a fixed bonus to hit, but scaling bonus to damage.
