Do you still use the .phpstorm.meta.php file? It seems to cause an unforgivable slowness in code-completion when it exists for me (and it doesn't work with multiple-argument methods, like the entity manager find method).
About a month ago, I posted on the Xenforo forum about the trouble I had with the software. Once I had expressed my frustration, I gave you an opportunity to delete the thread. You did.
I shut down my bulletin board. If you want to know why, I can send info.
