I think I speak for most of us when I say I only play the game because of HonorBuddy.
Because of the recent Warden scares, I find myself offline most of the time, compared to when HB is up. I'm just not the gamer I used to be and find HonorBuddy to be a lifesaver when it comes to WoW. Work is about to start back up, so I won't have so much time to play like I did during the summer break (I'm a teacher). I just don't find any enjoyment in focusing on what skills/abilities I need to use at what time, when I can have the bot do that for me, while I just focus on keeping my butt out of places I shouldn't be. I can focus alot more on work when the game is being played for me and I can enjoy the nitty gritty of the game when I have free time.
TL;DR
I only play because of the bot.
EDIT: If there is a Blizzard employee on this forum, I hope they see this thread's poll. If anything, HB is generating more customers for them! Hah.
This post just about explains it all (not to mention carpal tunnel/tendonitis - this saves what's left of my hands/wrists). If they shut HB down, very small chance that I'd continue to play.
