clarkwinkelmann have you noticed significant improvements in using Cloudflare with Flarum ?
I didn't use Cloudflare Then and don't use it now, so I cannot answer your question.
I'm using a SSL connection to offer a maximum of privacy to my users, so I don't want to give this up lightly. Especially if I'm dealing with a US based company (which I don't trust the least due to US governmental requirements). That's not because the contents discussed in my forum are so sensitive, it's a matter of principle for me.
Furthermore, the advantages of Cloudflare aren't very important for me. My website is in German and therefore not accessed from all over the world (it's hosted in Germany now btw.). It's not making money, so the risk of DDoS attacks is less of an issue for me as well. And as I said, bandwidth is not very expensive nowadays.
