The Field Repair Bot 74A and Fel Iron Toolbox has seen quite a few changes on the Blizzard's World of Warcraft Public Test Realms. Players will be happy to know that the repair bot is now stackable and has had its build materials decreased substantially and the Fel Iron Toolbox can now store more items.

The Field Repair Bot 74A now only requires 16 Thorium Bars and two Fused Wiring. The fewer reagents needed and the item's stackability should make it easier for Engineers to stock more field repair bots in their inventory. In keeping with the engineers' new space saving changes, the Fel Iron Toolbox can now store motes, primals, and blacksmith hammers. This should allow players to store more of these elemental ingredients.

Hopefully, these changes are retained when Patch 2.3 goes live since it addresses some of the space issues that long-time engineers have been complaining about. In any case, we'll probably be finding out soon enough since the first part of Patch 2.3 has already been released.
