You should hit... Read All Sometime after Diablo III Reaper of Souls I was hoping we'd get another proper expansion. It seems instead of getting a full expansion we've been getting a ton of updates that if you bundled them all up would equal a full expansion when you consider the Necromancer class coming this year. I still would love some more story to see what happens after Reaper of Souls and try and wrap up the whole thing that happened to Leia but... I have honestly no idea what the future of Diablo III is. That said, Blizzard still seems hell bent (rimshot) on updating it with really useful stuff and the latest 2.5.0 patch is icing on a cake made of... pure evil.
You should hit the blog post below for information on the full patch but the short of it is that there will be a new interface for crafting materials so they no longer take up inventory slots. That alone is worth the price of admission but 2.5.0 also contains The Armory which gives each of your characters 5 unique armor loadouts you can toggle between. On top of that they are adjusting the rate at which certain Adventure mode zones spawn making the ones that show up a bit too often less seen. There are a couple other things in 2.5.0 so hit the link below for more details.
And if Blizzard is reading this... please... Another couple acts of Diablo III please?
