i've been playing support pretty much exclusively since s4. i occasionally play other lanes, but support is where i prefer to be most of the time. its VERY clear that this preseason was a HUGE nerf to supports(unless youre senna. then its tailored to your exact playstyle).
i don't know how anyone who regularly plays support would see it as anything different. i really get a strong feeling the people in favor of these changes are actually just people who think supports should be nothing but ward bots.
