Guild Wars 2

I just have a few questions that people may know the answer to about ascended weapons. Sorry if these have been answered somewhere I couldnt seem to find anything with the search (it gives me back 0 results for some reason)

1. are they random drops from the fractal, or rewarded based on some metric (completed section/run, tokens, ETC?)

2. From what I can tell, the upgrade slot, and the stats are “intrinsic” in that if an upgrade would give say 20power/14vit/14 tough, the ascended gear would have that built into the “base” stats is this correct?

3. Assuming #2 is correct. Is every stat combination possible? Because that seems, absolutely mind numbing to me. If we assume #1, 2, and 3 are correct. If an ascended piece drops for me, there is a 1/3 chance it’ll be the right armor type. 1/6 chance it’ll be the right armor piece, 1/12 (I believe) chance that it will carry the correct base stats, and then 1/12 chance it’ll have the correct intrinsic stat. Which seems… ludicrous to me.

just some quick yes/no/we dont know yet answers would be much appreciated.
