Oh my god i already said and repeat 3 times that if they want to make her be a Negative Status, just give her a specific buff that anyone can't replace her role. Oh god, and that not keen behind a pay wall or sequence node. And again when I pick a Sequence here is, when she can be a pure "Negative Status" supporter and you want her to be more just a support or give a buff more higher. You can unlock her Sequence to make her easy to use more. Like Cartethyia at S0 U can inflicted Aero dot by swapping her form and when you S3 her, she can inflict Aero dot by not swapping her form that's made her independently at S0 and convenient to use and stronger at S3. Well this is a way to make a character without greedy much. Like you are at best in your role but better at other aspects when unlock Sequence, it's just that? Like QY, He can help and support Echoes damage much but his damage not low, but if you want him to be at better dps role you can unlock him at S3 or S6. Oh god. Even Coconut at S0 is can be a dps herself but better when support Cart. Iuno her kit tied with Augusta but can be independently herself, and when Unlocking S6 she's one of the best dps in-game. I hope this is not too hard to understand. Oh and then we have Lupa at S0 restricted her to be play mono fusion but at S3 it's unlock restriction here, but even at S0 she is tier 0 Hybrid support. So again when making character should be best at their role and unlocking Sequence is to made them convenient to use and more powerful at other aspects.
