I think before this crafting system will be effective and profitable for crafters, the effect of stats on gear on player performance needs to be improved. It wouldn't work well if for example, we can tailor a piece of armor to give a few extra points of +dexterity only to find out it will only give us +0.001% increase in accuracy.
And in topic with crafting, I'd like to be given a better description and/or more apparent effect on crafting stats too. Right now, it's so hard to find out what synthesis is affected by what crafting stats, and the extent to the effect (if that's even what the stats are doing at the moment).
