You’re welcome to make such a suggestion in the General Discussion forums. CS is not involved in those decisions.
Having read many threads with these sorts of “comments”, they don’t tend to boil down to the game not being playable, but rather, not exactly perfect or not what they want.
For the most part, the game is absolutely playable.
I’m not aware of any recent DDOS attacks. Was there a Blizz post on this that I missed? And yes, those are actually considered illegal and not recommended.
