More personality to animal companions is nice. During the weekend I started new playthrough (with TB mod, which I found great and can recommend it) and one of characters I created was sylvan sorcerer.
About 30 min later in game I realized I probably forgot to name my smilodon companion. So I went through character creation again just to find out its actually not possible to name your animal companion. What a shame, this begs to be implemented.
So thumbs up for animal companions progression
.
(At the end I went with paladin class, but who knows how it would influence my decision-making If I was allowed to have Smiley as my companion
)
