Both feats and multiclassing are optional DnD5 system, any info about those 2?
For me are feats the most important ones, they allow new types of characters like a mage slayer(like dragon age Templar) or a sorcerer that specializes in sniping enemies with spells from far away.
In the hunderds of hours I played NWN have I barely multiclassed at all, I only multiclassed when it was required to unlock a certain prestige class. Still would I like to have the option, but it is not that important. Baldur's gate had a lot of muliclassing but old DnD had a far more generous multiclass system than d&d 3, 3.5 or 5
