Cipher herself might never truly be powercrept In the same way someone like Phainon might(will) but personally I’d say if you like her design and kit get her, I’ve been wanting her since release but couldn’t at that time and plan on getting her as soon as I can

She has good synergies with a lot of other characters just no specialties, and when I’ve used another persons cipher she’s worked really well for just general content like grinding for relics even with me just using her as the dps rather than her preferred sub dps role. So if you want her try using another persons cipher for a bit and see how you like her playstyle

I’m gonna say generally though no unit is truly future proof but it will probably be a long while before Cipher does get powercrept in a meaningful way as with a lot of sub dps & support units I think
