All of you who are saying that this just adds another trip you OMG HAVE TO TAKE to have a shot at Worlds, well, sorry, but I laugh at you.
Unless the Best Finish Limit changes, you're COMPLETELY off base. If we assume it doesn't change, you STILL only get to count four tournaments, out of 3 possible STPS and 3 possible Regionals. Last season, you STILL only got to count four tournaments, out of 3 possible STPs and 2 possible Regionals.
They are giving you more options of what spray of tournaments you choose to go to. 5 opportunities or 6 opportunities, the number that will count is exactly the same.
If it comes out later that the BFL is increasing, then go ahead and complain your socks off then. But until that change occurs (if it does at all), you have ZERO reason to complain.
You seem to be completely ignoring the fact that, the more tournaments you play in, the better your chances are in doing well at at least one of them.
TCGs are inherently somewhat luck based. No matter what you do, no matter how good you are, luck can shoot you in the foot. For example, despite getting 1st and then 4th at 2 separate State Championships, I barely whiffed cut at Regionals on resistance. Missing cut on resistance is purely luck based, and I couldn't control that. Because I was only able to attend 2 States and 1 Regional last year, I had NO chance to reach the best finish limit, and my poor luck at ONE tournament really killed my CPs. I couldn't get the the 4 tournaments all counting towards my CPs, and the one tourney I did poorly at (Regionals) gave me almost no CPs, and I had no way to try and make that up by playing in another Regional. Had I attended a 3rd States and a 2nd Regional, I would have had two more chances (out of a potential 5) to beat the variance and eliminate the luck factor, and probably pad my rating a substantial bit more.
The simple fact is, the more tournaments you go to, the more likely you are to hit the Best Finish limit. Think about City Championships. The limit was 5 (I think? I could be wrong here, it was around there, but I'm lazy and don't want to look it up). If I attended 5 Cities, I could in theory reach the best finish limit. But the odds, looking at pure luck, are pretty slim for that. If I attended 10 cities, my chances of making the limit are far higher. 15 cities? Way, WAY higher.
This applies to 3 Regionals. Attending 3 States and 3 Regionals give you 6 shots to earn points in 4 events. Attending 3 State and 2 Regionals gives you 5 shots to earn points in 4 events. Attending 2 States and 2 Regionals gives you only 4 chances to earn points in 4 events, meaning you CANT have a bad luck streak at ANY of these events, or your rating is in jeopardy. Now imagine going to 2 States and 1 Regionals like we use to have in the past; You had better do incredibly well at Cities if you want an invite going to that many Regs and States.
So, honestly, you really DO HAVE TO go to all 3 Regionals to have the best shot at a Worlds invite. You can get an invite without it, but you rely much, much more on luck if you don't go to all 3. And truth is, most people can't go to all 3. Many people couldn't even get to 2 this year.
The other issue is with the locations of events. If we aren't increasing the number of Regionals, that means far greater travel distances to attend the 3rd Regional. Imagine this scenario; I play in Utah. Last year, to get to both Regionals, you had to drive ~9 hours to Colorado (albeit, it'll be in Utah this year), and ~10 hours to Southern California, and you have to pay for at LEAST 4 nights of hotels. That's extremely expensive and time consuming. Now add another Regional. If my guess it correct, the 3rd one would either be NorCal or some place much, much farther, like Texas or Washington. That AT LEAST another ~10 hour drive (probably more), and another 2 nights in a hotel. That is incredibly, INCREDIBLY expensive, and to be quite blunt, the prize support at these tournaments does not, AT ALL warrant that kind of money being spent, considering that there are also 3 States, many Cities, and Nats to attend if you want to get an invite to Worlds.
Anyway, I guess the TL;DR of this post is that THE 3RD REGIONAL IS NOT OPTIONAL like you are making it out to be. A truly competitive player is essentially forced to attend the 3rd Regional or potentially forfeit their invite chances. And that's not cool.
(Thank goodness I'm not really going to be playing at all this year. Even if I was playing this year, I couldn't afford to be serious about it at all. The 2 Regs system was already sorta pushing it for me; 3 Regs just breaks my budget.)
