The experience of playing World of Warcraft: Legion through a Radeon RX 5500M 4GB is going to get a very strong 104 FPS. Note that those results would be running at High and 1920x1080 screen res.
The 57 FPS on 1440p ultra setting seems to be a very good choice for running this game with this GPU. But it can also be pushed up to 4K, should you wish, where it can get 47FPS on High 4K or drop it to Medium 4K to get 70 FPS. For the 4K High setting it would cost $0 per FPS, or drop to $0 for each frame on Medium 4K.
In summary, if you are looking to play World of Warcraft: Legion in Ultra then you have come with the right graphics card. The Radeon RX 5500M 4GB can chew through the graphical performance needs of the game with relative ease. 1080p Ultra will return 75 frames, then the larger screen resolution of 1440p can deliver 57 FPS, with the 4K resolution seeing 34 FPS in Ultra as well.
