The day MA starts dropping enough uber items like Helenas, is the day EU is dead. No, I mean it. The ones carrying this game are the ubers - there is a 5% volume in this game who deposit/spend more than the other 95% combined (crafters/miners/hunters combined) who have invested and spent thousands and tens of thousands of dollars over the years in EU, with the ever-increasing value of their items... yes, some were gambles that could easily be handled, but others... not so much.
If an ubers investment 'portfolio' turns into something worth ~10% of it's original volume in ~12 hours (or a week, or a month), that is the day they will leave. You do NOT want that (although it seems MA might, for some ungodly reason). You, me, the average player combined in our deposits/expenditures does NOT equal even one employees annual salary.
EU would fold if enough of the ubers left and started selling their stuff. If only 3 of the ubers I'm thinking of put up sales threads, market would crash even further than most would think possible, especially if they put up their ENTIRE inventory for sale.
And that's not counting what it would do to the skill market if the ones who were eating these "cheap chips" decided to leave due to this bullshit.
Seriously though, if you've been here long enough, you should be able to clearly track the domino effect of A > B > C > ohshitwearescrewed...
