If she basically likes WoW, she could - should more like - give FFXIV a shot. Way more story driven than WoW, very single player friendly with npcs jumping in for mandatory dungeons and a great world. Plus, base game and first xp are forever ftp - that’s hell of a lot of content. Community is one of the most friendly communities I’ve seen in an mmo so far - sure there’s the rotten egg here and there but they are very rare. Toxic behavior usually gets you kicked, not the ‚bad‘ player you were being toxic about. As for cute pet, there is a pet class too :)

Oh and the devs play and care about the game and seem to be in touch with the community. They made like a press conference where they apologized because they had to delay the release of an expansion for a few weeks. And gave free game time. I’d give it a shot :)
