We know from experience that they sometimes read the class forums over there, and sometimes read them over here. More importantly, I made this thread to ask about whether this book was gonna be an issue, and I think it will be. I tweeted Holinka, and AFAIK he hasn't replied or cared yet. I'm not interested in spamming a discussion forum with crap, I'm much happier saying my piece. The game has had MANY balance issues and several design problems over the years, and no one's experience is improved by hysterical players.
But definitely tweet Holinka, and if you feel like it, make a thread in the official forums. The moderation there is so poor that it's pretty much not worth my time, but it could be worth yours? It's worth letting them know that rogues don't want this kind of bullshit, and what it gives hunters is the lulz, and what it takes away from rogues is the entire meaning of stealth, and the entire reason to pick the class. That's worth everyone standing up and saying. Once.
When you are standing around stealthed on your druid in that place, you'll feel like you should in stealth- a careful assassin or a stealther waiting for the correct moment to project force for your faction. When you are stealthed on your rogue, you'll know you are the worst guy for that job, because a shadowmelded warrior (not rogue), a camoed hunter, or a prowling cat are all much better at your only job.

Of course the stealth has counterplay. But it doesn't have:
1- A shimmer effect to reveal your position.
2- A short duration with a long cooldown (20 seconds of stealth every 30 seconds).
3- A need to stay near shadows, structures, or undergrowth (you can stealth in an open field)
4- A need to stealth at night (you can stealth at high noon in plain sight)
5- Physical signs of your progress (footprints, waving grass).
There's ways to do stealth without using WoW's model, but in those games stealth is much weaker, and stealth is a bonus, not a necessity. WoW's rogues need stealth and are designed around it.
