BranjoHello: Installed it and tinkered little around it, but I'm not using it regularly yet.
You really don't have to use it regularly like you do with Steam, Origin or Uplay. The thing is it's essentially just the old downloader with optional client features and a new ui, so if you just want to download your games and install them through it or just download a installer like you would the downloader and nothing else, you can. Just because you could use it for other things doesn't mean you have to or feel obligated to do so.
Having read this thread it feels like people miss that point(that when it's finished it will just be a fancier downloader with optional client crap you can just disable). I guess it's due to the stigma that comes with the "Client" label thanks to Steam, Origin, ect. at least that how it reads to me at any rate.
