I find that things in life are rarely black and white. I'm not averse to compromise- something in the middle might be acceptable. The 2nd choice would help to allay my aversion, but would still leave a sour taste in my mouth. A Wintergrasp/ Timeless Isle type solution would be a better choice in my opinion.
Having said that, I have faith in Blizzard doing what they can to make their stockholders happy. Some of that translates to keeping the players happy, but not always.
Say, for instance, they had an issue with people finishing the content faster than they can release it, then unsubbing until there was new content to justify their $15 a month. What could they do to make the content last longer? Would they do that thing? If they did, how would they justify it to their fanbase? By explaining that they simply can't have everyone unsubbing all the time? Or by saying, "Hey guys, this will make the game better?" I'm not saying that's what's going on here, as I don't have access to the inner workings of Blizzard. I do, however, have a decent understanding of business, and it isn't an unlikely scenario, either.
Regardless, as I said, I have very limited gaming time, and I simply will not spend it doing things I don't want to do. If flying is never allowed in Warlords, I will not purchase it. This isn't a threat to Blizzard, or me being whiny, it's just an informed consumer stating a fact.
