i150? That's to assume that there will be no expansion set until after Sept 2015.

In Mar 2014, 2.2 was introduction with item cap i110 that is to last for 6 months, which is to Sept 2014. Assuming no expansion till then, patch 2.4 will probably introduce i130 that will last through Mar 2015. And this comes with the Third installment of the Binding Coil, which some of us already can tell who the final boss would probably be.

Yoshida says he aims for the expansion to happen within 2 years form ARR launch. Personally I think patch 2.6 doesn't seem possible, because he would have to introudce the forth installment of Coil with i150 by then.

So I doubt there will be any major changes on how gears would go until expansion set. So I don't think we will see some i150 shields with some crazy blocks.
