Just pandering to the big clubs yet again.
Imagine it next season - Things aren't going you way Pep/Shippmann? - I know, you can bring on 300 million quids worth of attackers against newly promoted Fulham who have 3 yts players to come on - it just further queers an already queered pitch.
Now, If they made it part of a rule where the two additional subs have to be from the academy/u23s or you can't make the changes and can only have 3 subs max, then I'm all for it.
It would make all teams play the younger players more regularly, especially the club's who have signed loads of young players who can't get near the 1st team.
