"I live perfectly fine with 50k a year, why do people need more? Stop buying shit!"

No, it's just like hoarding in real life. Pretend Blizzard gives you a brand new house. You're happy with it for years, nothing is wrong with it. Until a new shopping mall opens up down the road from you. All of a sudden, you want to buy EVERYTHING the mall has to offer. Wow, you're out of room in your house. You possibly can't store anymore junk you've collected at the mall. So now you start to complain and whine to Blizzard that the house they gave you isn't big enough, and demand that they build a 2nd story onto it for you.

Or, you know. You could stop collecting all the junk.

Don't get me wrong. I'm not saying that Blizzard shouldn't ever add more tab space. But I can guarantee you that 95% of the people who complain about it are hoarding the most rediculous shit. Crap they will never use / touch. As others have said before. Even if Blizzard does add more space, it'll never be enough. Because there will still be thousands of people out there who pick-up every shitty item they get and go "wow this is so awesome, it'll go perfect for that really off-the-wall Wiz build I wanted to try out a year and a half ago". 2 days after Blizzard expands the stash to 20 tabs, there will be 95729835 new posts on the forums going "GG Blizz, you add more tabs but not enough. I'm already full and can't hold more, add more tabs already, geez!".

No matter what Blizzard does, it'll never be enough. The only way to solve the issue is to teach people that not every stupid item they pick up is a special snowflake. If you aren't going to use it within the next 2 weeks, destroy it. Who gives a fuck how good it rolls, you'll always be able to get better. Your Monk does not need 19 different sets of gear for weird ass builds you want to try. Or maybe it does. And in that case, deal with your shit stash space ya hoarder. Don't make your problem ours.
