Are you bound to specific DoH/L classes again?

[Bearforce]

my thoughts, you need to be bound to dol/doh and its worthwhile because A) the more materia attached to a gear the more you become powerful B) enemies now are much harder to kill so materia is a must C)all in all lvling crafts is a must because attaching more than 1 materia might lose your gear+ makes you save your gil if you want to create another gear instead of buying it in the MW
