This game has a lot of game modes and also plenty of possible team compositions. Just because you see a character on a lower rating doesn’t mean you should not use them ever.
Lastly, this tier list is focused on overall PVE usage. I don’t have time to make multiple tier list to divide it further since it’s mostly just me (sefhi) maintaining it.
