well i favor skill speed after u reached a certain crit point cause even if crit now also give you more crit dmg its always good to get ur shots out faster or at all thx to our casttime.
also the determination nerf doesnt affect us very hard but once u turn off ur WM it might be a problem wich is the reason i dont focus too much on that.
so its pretty much a good mix off all 3 stats for me and that works pretty good actually.
