Why "past subjunctive" has this (confusing) name if it is used for hypothetical situations and wishes that take place in the present and the Past Perfect is the tense used in such contexts in the past?
- If I were you, I would not do that.
- If I had been you, I would not have done that.
- I wish I were there.
- I wish I had been there.
Wouldn't "Imaginary Present" or something similar describe better this verb tense? If so, why isn't it adopted by all grammar texts?
