You need a LOT of any of the secondary stats(crit, direct, etc) for them to have a noticeable impact. Its not something to get too worried about before you start to reach some of the end-game gear levels. As an example, if you took the very best level 50 gear and somehow got each piece to give you the "ideal" secondary stats(which you wont - stats are only customizable on relic items so you tend to end up with a bit of a mix and match in the end), you would have 290ish of said stat. The bow(and only the bow) of the current top-tier set has 500 of this same stat. So dont get too worried about it yet.
