I also think its a good idea to stop buying series if all you're buying them for is Jean Grey teasers.  I do like Avengers versus X-Men and will get the whole series no matter what.

But back to doing business with a company, if you really don't like the way the company is doing business, why give your money to them?  It doesn't make sense to support something you hate.   So anyone disappointed with anything at Marvel should quit, because in truth the only think that affects a business is SALES!!!  Vote with your pocket.
