What is a Duo you really enjoy playing and why?

For me it's Bennett and kazuha And I know most people would say that's kind of overdoing it on the buffs, but like it makes whatever character I'm using them on really powerful (at the moment that being arle) Not to mention like their burst basically come up at the same time for me So I love just being able to put Bennett's burst down and then use kazoo's burrs then his skill so it groups enemies into minutes circle and I can do both of those setups while waiting for arle's skill to be ready I am now understand why people said Bennet is like secretly a five star. I underestimated him a lot until I made my arle team And they are just so good together
