Not quite. See, Artist is a result of Reality's desire To Be outstripping Tokitoki's egg production, though she herself is unaware of this. Even without the whole 'literally incapable of feeling without substance only obtainable from creating a timeline' problem of her existence, she's driven to create without any rhyme or reason. She's not really a good person, she just recognizes that being good is less trouble than being bad, and that it feels good to be good more often than it does to be bad. She's Chaotic Neutral on the DnD alignment scale. Being constrained from creating timelines is her worst nightmare. Not losing people.
She doesn't care all that much about the timelines she creates, just that she create them. There's already plenty of blood and tears in the normal story, so there's no need to add more to make it interesting. A story where everything is horrible forever is boring, and she avoids making 'boring' timelines. She's never going to make an Immortal Frieza timeline, because then he'd be essentially invincible, since about 99% of the universe couldn't stand up to him in his weakest form. What's more boring than an invincible hero? An invincible villain. An immortal 'Future Trunks' Gohan? Now, that could be interesting.
@PoptartProdigy Looking over the Trunks Style. Would the QI blade used by one of Cooler's minions work for that? I mean, it just says sword.
