I used to use FW exclusively too (not going to say what version as I'm even "cheaper" than you)...but switched to Adobe CC 2 months ago and can't imagine going back. Considering what you get, it's worth it IMO. Even though FW is part of CC, I find I do everything in photoshop now, and you may find After Effects, Illustrator and Premier are more useful than you think for video content and more on the web. Even at $50/month, in three years you'd have spent about what you would to have upgraded the old CS packages, and as Henning said, you always have the latest version of each program.
Given all the tools in the CC package, I encourage you to give it a try, I think you'll be happy.
