For me, Dungeons and Dragons died after 3rd edition (3.5)
Now that were twenty years of happy gaming I will not forget. But.
I played a single warrior for over four years, reaching a ludicrous level. Every battle was the *exact same.* "I stand overhere, I go in Defensive Stance and will attack anyone coming near."
And that's what I did. Surely, I could have picked something more exciting and 3.5 was all about the multiclassing, but as a warrior class you had *nothing* to do but roll dice and add/subtract. It was a pure numbers game.
Compare my Fighter 6 / Dwarven Defender 7 / Weapon Master 7 to a level five Battlemaster in 5E, and the latter one is just SO much more active and tactical to play. I *love* 5E. My group has unanimously voted to never upgrade. Things are the way they are now, we have the books we need, we're good. We'll homebrew something in if we feel the need to.
And, truth be told, I doubt the Wizards stick to what they say; the whole 'no new versions anymore' thing. Their whole business model is to redo the whole thing so everyone buys new books. If they just bring out new races and classes and whatnot - I can just look those up on the web and add them to my game. They'll never sell another thing. I don't know. We'll see.
