Cyril and Methodius didnt really bring any positive influence to Slavs.
We probably wouldn’t even call ourselves Slavs today if it wasn’t for them. Many of today’s Slavic nations would be partially or fully assimilated into other nations if we didn’t start writing down our language. Pagan Slavs probably wouldn’t do that. But I agree that the extinction of the original European pagan religions was a big loss, despite of what @srdceleva thinks about it.

It could also be schizophrenia. 😮
