Pretty sure Jacopo mentioned in the last Q&A (or maybe the one before that), that everyone will get a free Attribute Reset and that Attribute Reset will be content of the Cash Shop. There will be a decent cooldown on the usage of that though
We will be able to get additional Attribute Points through gear and the Talent Tree but I think they hard cap at 25?
The only concerns I currently have about the system would be wether it is too simple and that the Attribute Points one currently gets might be a bit too many.
