As I said in another thread, I really think 4e's design was a double-edged sword. As many people liked it as hated it.
5e's deliberate inoffensiveness and "blandness"(I'm not using that as a criticism per se) is actively working against it here. When times were good, it worked well, few were especially upset at the idea of playing 5e, but it's not the kind of game that inspires fervent defenders when times are tough. Rather, it's the kind of game where you think "Hmm, this is good, but it could be better if I just.." When everyone is involved in the 5e ecosystem, that's really effective design, because you can find the 5e mod you're looking for! But by actively kicking everyone out, now they've unleashed the desire to "really fix" 5e that's been bubbling for years. We've entered the era of 5e Heartbreakers, and nothing is stopping this train now.
