"Cannot Link" pain

So since one of the recent updates, we now appear to get "cannot link in this area" messages everywhere. I read that it was to prevent previews of hidden armor.

Here's why it sucks: we can't link or use a link for class builds anymore. Is there a way around this? Because I never did find an input for class build links on the Hero panel, and now builds cannot be shared.

Or, more specifically, builds from places like Metabattle cannot be used or shared.
