Players leaving the game is understatement. Konami can't please everyone, but they still got the money. And I bet they know their best marketing strategy, so really, when players leaving the game because of this, pretty sure most of them are minority.
As for me, I don't find #2 a bad thing, personally. Since I'm a casual player and I can always ask people I know to play with me, and I can negoitate on what kind of deck we could use. This avoids fighting OP thing when I don't want to play competitively. However, indeed it'll be bad from another point of view, such as if you're playing casual, but you get matched with random people either in internet or IRL that uses competitive deck, since you'll be easily wrecked by today's powercreep.
Calling me Kaze or Kazemachi is as legit as calling me Eria.
