3v3 needs to be the new standard or else we fall into the same pitfalls we have now with a stagnant meta. With DX releasing, all we are going to see on streams are the new DLC characters people have been wanting to learn which wont be any different from the Suicune/Lucario/Braxian/Lamp/ majority driven matches we have now.
3v3 will require you to learn more but will give more a viewing pleasure to the audience that Pokkén needs in order to gain interest from not only long time viewers but new people who like the game but want to see more. Yes the matches will be a bit longer and the rules around Support and Synergy are different but overall I believe 3v3 will provide a new staple that Pokkén should embrace for not only the players but for viewership.
