Does the Azure Dragon Crescent Glaive teach bad habits? (and noob build advice)

This might not be the clearest question - I’m not sure of my own thoughts myself, honestly - but does starting with the Glaive train bad gameplay habits? From my research, I’m not worried about whether it’s OP or not, but I wanted to ask if anyone who’s mained it for a long time had a hard time switching to a different weapon that didn't have a parry fable art.

I’m starting a fresh run after I fell off last year (stopped after the furnace boss, can’t remember why, gonna finish this time!), and I like the idea of keeping and upgrading the same weapon from start to finish, but I’d like to stay open to new possibilities.

Also, asking as FromSoft vet, is there a common wisdom on when/how much you should level vitality, vigor, and capacity? It’s never a bad idea to pump vigor before your actual damage stats in DS/ER, so I’m wondering if the same applies here.

Thanks in advance for any advice!
