Tell me, how exactly will Survival and OW become any closer to each other if a clan system without clan tags are implemented?
Please keep in mind "while you think of what to answer", that clans "already" exist in both game modes, and in BIG proportions too whether you like it or not AND whether it's official or not - Already. How will this implementation create "more similar" scenario, scripts, maps - as you like to call it, HOW will it become more similar than it already is?!... You can't just say a lot of things of what will become without giving any technical reason to why that is, and how you came to that conclusion! Therefore everything you say is totally invalid and have no meaning what-so-ever.
You're really making a fool out of yourself, so sad you can't see it.
Also keep in mind, that Survival and Open world is too different "GAME MODES", they are NOT two different "GAMES".
