I've heard of this thing called 'programming' that would allow the test server to just dump all the gear into the inventory of newly created characters with full heat, instead of making us individually purchase each item from the supply depot and run through the fast advancement level over and over in order to heat stuff.
At this pace, I'll be burnt out long before I get to test all the gear.
But the way it is, you can essentially choose what level of gear you want. If you want to test level 1 callahans, go for it. If you want to see how level 7 blasters hold up in a Vanaduke fight, do it.
The only difference I would make is let us be able to forge and change gear everywhere - not just arsenal stations. People would take advantage of it, yes, but this is a testing preview. Hopefully we're here to test things out, not abuse our abilities.
