Actually I don't think so.AND LFQW has been a problem for ages! (note, can't comment on 4e). If it was an easy problem to fix, it would have been fixed earlier. Finding another good solution might be *very* challenging.
The real problem has always been to confess to yourself that it really is a problem, and fixing it is worth fighting the conservative segments of the player base.
Actually, I don't think the actual mechanics are very difficult to solve at all. I think the real reason this took so long is because it was so hard to let go, and having the courage to change it despite knowing how conservative ttrpg:ers can be.
In that sense maybe it couldn't be done without WotC facing a catastrophe. If 4E had done better, maybe the drive to truly evolve would have been smothered by cautiousness once again.
That 5E was such a huge success meant the outrage drowned in the influx of new customers, which made it an easier buy.
Just look at these forums and how they've changed since 3E. If you or I dare to criticise even a small part of 5E loads of people reflexively jump to its defense, no matter how indefensible it is. Which suggests we have a new Holy Writ, and it will be decades until WotC is ever again able to meaningfully take a step forward with their game design... :-/
The wait for edition 5+ is gonna be a long one, certainly if Paizo really is failing to step up (and everything about the PF2 playtest indicates that to be the case...) Sigh.
