Well I trust my source of testing more than anyone else (because I saw the results for myself). I just dont want people to talk complete ***. I mean you can FEEL the difference in misses with low and high dexterity.
Didn't you say yourself that the stats are broken? So why does it surprise you that some stats work differently on other classes?
The real problem is that (all) stats are useless because their effect is too low compared to the effect your rank has in regards to Damage/Defense/Accuracy/etc. Thats why the 'only" usefull stat is Vitality.
