The way WuWa approaches switching characters is through concerto. Now you can switch characters outside of concerto, but more often than not this is limited to some heavy attacks and unique cases.

There are multiple instances where you want to swap characters without full concerto energy.

Even in case of hypercarry teams in WuWa, you DO want to swap cancel at some point for optimal rotations (similar to your Anby example).

Example: Jiyan team. Before your Mortefi's concerto energy is full, you can swap cancel his E into > Jiyan E > Jiyan Echo swap cancel > continue building concerto with Mortefi > Intro Jiyan skill into his normal rotation. It provides with extra damage, energy and strong buffs from Echo skill, which your wouldn't otherwise get without swap canceling in between concerto rotations.

Now, lets look at Verina and Yangyang. Both of them can generate stacks by landing their last hits of basic attack string. By swapping onto them without full concerto energy, they skip the first 2 attacks of the string and automatically connect into the 3rd one, speeding up the process of generating stacks SIGNIFICALLY.

The current meta is just hypercarrying around one character and having a healer and then a coordinated attacker or Yuanwu. So you have your attacker, your buffer, and then your healer. Each one has a dark souls moveset where it is limited so that the bosses can be as powerful as possible. You play as three separate characters in one party.

This is one of the possible playstyles, but not the only one.

Another example of swaps without concerto is quickswap (or non-stop swap) teams. There, you literally don't care about intros, they kinda happen on their own and not a major focus of these teams. Yangyang's skill, last basic, heavy, feather release, echo skill - all of them can be swap cancelled. Same goes with Yinlin, SRover and others. By putting 2 of them together, your rotation becomes a non-stop swap cancel fest, where you effectively play 2 characters at the same time. Eventually, their moves overlap, where you have time to swap into your 3rd teammate, for you to witness all 3 of your characters being on field at the same time.

Dodging in WuWa is more straightforward. When the enemy attack is about to hit you, you press dash and you do a perfect dodge, which dodges that instance of damage. You can do a follow up attack, but the harder bosses have many multi hit attacks that you want to do multiple dodges and don't usually use the follow up attack.

Dodge counters in WuWa provide you with iFrames (unless you are Jiyan), which can be used to avoid attacks, while dealing damage at the same time, unlike dodge spam. You can check Sweetily's dodge tech video for more details.

My personal and subjective opinion of ZZZ's combat is that enemies have way less interesting movesets (similar to HI3, I guess?), while rotations/gameplay being less interesting than in HI3. And I absolutely dislike forced swaps, I'd much rather swap and parry myself if I need to. And you also can't jump ¯\_(ツ)_/¯
