This should go well.
This is already going well. What is this, "Let's renew an edition war" month?
Missing the point.
There are all sorts of very, very good reasons to dislike 4e. Combat grind - 4e combat was LONG and there's no real argument to be had there. There's a very good reason that 5e combats tend to end after 3 rounds most of the time. Finicky - 4e was chock a block with tons of finicky little status effects. My 4e group had a mini-game of how many effects could we stack on a single target. The record was 12 IIRC. TWELVE ongoing effects on a single target! Or, you could simply dislike the 4 Roles setup, although, again, that gets more into presentation since classes were not really limited by a specific role, it was more just a tendency, but, again, I can totally see how that would turn people off.
The problem is, people didn't fixate on those. They fixated on things like, in this example, saminess. Ok, fair enough. I'd buy the argument IF we didn't have 5e right there with its "all casters progress exactly the same" and "almost all class will have spells" and "identical class feature structure". Oh, look, it's 4th level, what did your character get? He or she got a stat bonus (or feat if used). EVERY character. It's 6th level, your character got an ability. So on and so forth. Every class is identical in it's power structure. You could rewrite the 5e PHB using a single class chart (or possibly 3, one for each class that gets it's archetype at 1st, 2nd or 3rd level) and now, 5e looks like 4e. People would lose their minds if they did that.
It's all about presentation. The magic of WotC is convincing those that disliked 4e that 5e is somehow a greatly different game. It's not. There are far more similarities between 4e and 5e than differences, but, we're not supposed to call attention to that. And, frankly, there are those who could never, ever admit it because that would mean that they spent four or five years edition warring for nothing.
I have far more respect for those who hated 4e and 5e than those who hated 4e but now love 5e.
