There's loads of people with y/o nicknames where I work, which I suppose are perceived as a bit dull because they are so common and unimaginative. When I think about it though, maybe they are simple but also rather affectionate. Just interested in simple examples, Alexander to Sasha is a fair bit more sophisticated than Jimmo or Dobbsy.
Alexander to Sasha is a fair bit more sophisticated
Russian dimunitives certainly have more complexity than just adding o/y to the first syllable of a surname. You can also have diminutives of diminutives, e.g.
Сергей
Серёжа
Серёжик
