There will never not be a day I resent Moffat for not making McGann the War Doctor.
That could have worked as it would have been a sublime contrast to have the optimistic romantic 8th Doctor turn into a hardened and broken pessimist who is renewed as the guilt stricken but jolly 9th.
Alternatively I would have made the War Doctor a warrior woman (like Leela or Xena) and be very violent.
That way you would have got the whole Doctor can’t turn female thing out of the way and made the War Doctor something he would rather regret. Not because of the gender but because of the violence. Hurt’s War Doctor is just another Doctor. He’s much less prickly than some of the classic ones. There seems very little justification in him removing him from his own memory.
