Agreed tuan, im not a fan of changing the rule anyway, the field importance may be underrated, ok about thefans support but the home team can use many details.
For example, if you want to favourise action in the game, you make the grass a little wet to favourise possession and short passing, or make the field harder to play ( intentioally or not ) against teams that need to pass the ball more often, this advantages more the long ball style and aerial playing style.
For Camp Nou, for example is made to suit the style of the team, very big pitch that makes rival run and favourise possesion, some play in the mountains like in South America while its very hard for rivals to breath....
Some small details that have their importances in high level specially in the final game of the second leg where its a deciding game.
For the algorythm, i cant see any better change and it may complicate the rule for the new Football fans and practicers.
Summary: Blatter wants to alter the away goal rule in the knockout stage, as he said its quite old. The away team in the 2nd round has a possible advantage of 30 min extra. That makes sense. And for the first time, I completely agree with him.
I think it would be best if the away goal starts to count after the 30 extra minutes in the 2nd round (if applicable)

FIFA president Sepp Blatter has called for a rethink on the away goals rule and questioned whether the method for settling knock-out games still makes sense.
The system - where the team who has scored the most goals away from home wins the tie if the scores are level - has been used since 1965 in European competition and still applies in the Champions League and Europa League.
'In reality it favours the club that play away from home in the second leg. Where the scores are tied, that team has 30 minutes more than their opponent to score a valuable away goal. After all, in the first leg there is no extra time.' said Blatter.
