Yes I get that, they need penalties to decide the game and going to a neutral ground for that is a stupid idea but you want to scrap extra time because the home team as an advantage there while wanting to ignore the advantage they have for penalties.
Even now they have advantage of taking penalties at home ground, there is nothing anyone can do about that, unless UEFA wants to play third game in neutral venue.
Scrapping away rule gives unfair advantage to home team as they get extra 30 mins at home ground. With away goal rule, that was neutralized as away team got 30 mins to score one more goal which makes it near impossible for home team to mount a come back. There was at least fairness in that rule.
Away goal rule - Home team advantage as they get 30 mins in their home ground, away team advantage as one goal can knock the home team out, home team advantage as they will take penalties in their home ground.
This rule - Home team advantage as they get 30 mins in their home ground, home team advantage as they will take penalties at their home ground. Away team has 0 advantage.
The rule I said - Home team advantage as they take penalties in their home ground. Apart from that, there is nothing in that.
So it should be either 1 or 3, not 2.
