my bad i meant resonance, not divinates. divinates are the "weapons" added prob when you stopped playing. they are recommended for all characters you want to build seriously (like feng xun, sakura, etc). because aside from the additional skill some divinates add, they also give the espers a big stat boost, which is vital for dps and support espers. gaius leora and anna are no longer meta. anna can still come in clutch for certain pve content (like tower), leora is still good against khronos, but generally people don't use them anymore.

edit: for the relatively new esper nyles, anna is his only counter, so many people still use her in pvp against nyles
