I read around a bit more. Ohh hohoh there's a lot of backlash as well. People are split into either loving the new mechanic for attempting to balance an utterly broken game utterly hate it, just loath it. The latter group seems to be divided into the 'I can't play my decks anymore' or some variation of 'you can't just throw away two decades worth of legacy.' This latter one I only saw on jp side which makes sense I guess, tradition and all. Also because people see konami as wanting to make the big buckz off of this by rending a lot of old decks just completely unviable.
I'll try to add some context to the extent of the change for those not familiar with how the game works (or how the game breaks itself) and also because I don't know how far you explored it.
I explained this before here but, again, in yugioh you have a second deck separate from your main deck that you have access to at all times called the extra deck. With the addition of the new rules, there are going to be a whole five different summoning mechanics that work off of the extra deck. That's five sets of rules that govern how you can get these different monsters out of the extra deck onto the field. Like, that's ridiculous, but putting that aside, when you meet the conditions to bring these monsters out, you can play them onto the field by fulfilling those conditions. These days this is piss easy and getting a board full of them in a single turn is no problem for good competitive decks. Since this extra deck is always available to the player, the main deck has devolved into merely an engine to get these extra deck monsters out. As such, most archetypes for the past decade or so have their plays entirely revolving around the extra deck where getting one out tends to snowball into getting more pieces and getting more of these extra decks out. For about the last half year, the meta has been dominated by a tier zero engine that can start plays off of like a single card. How dominating? Like 90% of tournament winning decks feature this archetype level of dominating. It's that bad. And this archetype too needs access to multiple extra deck monsters in order to continue plays.
So what the new rules says is, you can no longer play extra deck monsters on the field anymore because now you can only play main deck monsters in those monster zones. Now, instead you can only play one extra deck monster in your single newly introduced extra deck monster zone on the field. Needless to say, this completely kills a lot of old decks and people are complaining about it. But there is a way to increase the number of extra deck monster zones on the field and that's by using the new type of card called link monsters which also reside in the extra deck, and these cards have freaking ARROWS pointing to other monster zones, and the zones pointed to by these arrows can be used as extra deck monster zones. Every new tv series introduces a new summoning mechanic and people complain about how its going to ruin the game but this one is getting a lot of complaints in particular because some decks are forced to use the new cards. Even the other past new mechanics weren't so obtrusive, they were merely a new kind of mechanic that was just there if you wanted to use them or not. Some old decks can't function without two or more extra deck monster zones and necessarily have to use these new cards. There's an inherent balancing mechanic built into these new link monster cards since the arrows can point to your opponent's side of the field too and give them access to extra deck monsters in that zone. As long as konami really does not fail to keep this check in place, I hope that this will balance the game more.
But I'm really looking forward to this complete overhaul because this game is completely broken and unfun at the top levels of play and creeping down into the lower levels too. The way you play this game now is to not let your opponent play at all. The name of the game is negation and floodgating. Oh you want to play that card? Nope, negated. So your deck is based on this certain summoning mechanic? Well I activate this card that doesn't let you use that mechanic at all for this turn. Like, the game already ended when you lost the rock paper scissors. Your opponent sets up a board you can't get over and good game. It's really horrible. So I'm excited because this backpedaling will introduce more interactions again in the game (what? a two player card game with interactions?? holy carp). But also worried because all of the stuff that makes the game utterly broken right now will still be there and all it takes is a little oversight or greed from konami to bring all that back in.
tldr; go prepare your popcorn
