I think you might have made the mistake of assuming everyone here likes 5E. There's been quite a few people heavily pushing for 6E for a long time. I think the first call for it was about a month after the PHB was released...
There's absolutely nothing wrong with this. 5E isn't going to be for everyone, and it's far better to play a game you enjoy, rather than try to pound the current edition into your favorite edition. IMO it usually better just to take the parts of 5E you like and insert them into your favorite edition instead.
"Better" is entirely subjective. 5E was extensively playtested, and for the most part it was made to appeal to the broadest base possible. This means that most people aren't going to be happy with every single aspect of it, however, most people are going to be satisfied with it. IME the hard core gamers, such as those who spend time talking about it on the internet with strangers, have serious issues with it. They (we) have a higher level of expectations, but we need to understand one really important fact: we are the minority. The problems you and I might have with the edition don't matter at all to the vast majority of players. If there's a 5.x edition, it will likely just clean up a few things, rebalance the most obviously problematic issues (ranger, maybe sorcerer), and update them to reflect new policy (races and alignment). A 6E isn't even on the radar at this point.
