One thing that many players don't like about this new mechanic is that players are kinda forced to use LINK monsters. I also think that this is a bad idea, unless there will be alternative ways to open more Extra Monster Zones.
In my opinion, they should make a new type of backrow cards (spell/trap). Something like a continuous spell card with LINK markers.
This will create more play styles. Either playing this new type of card and spam Extra Deck, or more backrow heavy. It will help to prevent players to create a board with many extra deck monsters while having trap cards.
