I agree. The game is pushing you, and not using the creature will sadly make the game very tough in some situations (well, the game is overall unbalanced after all)... I was hoping some kind of a "tamed animal" alternative will be offerd for those who dislike this necromancy thing, but sadly Larian didn't made any. I hope mods will be allowed in the future and somone will make a "tamed animal" mod alternative to necromancy or something, even if I gerneraly dont like relying on NPCs at all.
I use a creature simply because the game will be hard without one, but I really don't like this aspect at all, I'm surprised Larian didn't make any alternatives for players like us...
