When is a character a MUST PULL for you?
The most important thing to realize about Genshin Impact Meta is NOT who is the strongest character or team (although that is fun). The Most important thing is to get the units that most support YOUR favourite units. That's why I've collected the most often recommended 'must pull' characters, and ranked EVERY UNIT for each of them, so that you can figure out who is a Must Pull FOR YOU.
FIRST THINGS FIRST - pick your favourites

FURINA
Teammates Tier List
always remember that even if a unit is labled "best in slot option" that doesn't mean you NEED them. If you don't want to get a unit, there are ALWAYS other options you can find. These will just provide a lot of value and improvement over other options.
XILONEN
Xilonen Teammates Tier List
Neuvillette
BAIT! As a DPS, you shouldn't pull for Neuvillette unless you LIKE HIM and ENJOY HIS PLAYSTYLE.
This is the same for ANY DPS, such as Arlecchino, Mualani, Al Haitham, etc. DPS are YOUR CHOICE, and you should get supports to make your favourite DPS shine (if you have the funds to do so).
KAZUHA
Kazuha Teammates Tier List
Kazuha is a VERY Strong unit, and in skilled hands, can often surpass Xilonen in many teams. However, Xilonen is easier to play, hence why I have placed most units under "strong option" instead of "best in slot" option - xilonen just performs better for most players in my opinion. However in the right hands, Kazuha can be "best in slot" for more units than are listed.
In addition, when grouping is required, Kazuha is absolutely one of the best if not the best units in the game. So it can be very worth it to go for him for that quality of life, although grouping is less commonly needed these days than it used to be.
NAHIDA
EMILIE
Emilie Teammates Tier List
Emilie is such a strong unit that if you have a decent polearm, or especially her signature, her teams are VERY close if not equal to best in slot for many units (such as arlecchino) and are often easier to play, making her a very solid choice.
