Long term planing is certainly good, but I don't expect that from my players. I just want them to have a good time.
Honeslty, 5E does a great job of providing variety. I highly recommend not multi-classing.
The option to multi-class, as a game system, seems legacy.
Its a complication that creates issues for most players, providing a small benefit to a very specific type of player.
The amount of time debugging and validiating how it works, in a CRPG, is real production time.
I wouldn't be surprised to see it removed in 6E.
I would, considering it has a long tradition in DnD and they are attempting to make the next edition a "forever edition. You can multiclass for story or metagame reasons and frankly I doubt the multiclass implementation would be all that challenging in a game compared to everything else that you're trying to do. I rarely multiclass in tabletop myself but I'd miss it if it were gone.
