I probably wouldn't bother with an official parser if they decided to release one. Kparser seems to work moderately well and is handy in discerning what changes I require to change my personal build.

Although, don't forget that there are far too many variables that'll throw off a parse... and as of such should be taken with a grain of salt.

I imagine the people who would parse to figure out minute changes in gear probably already have one, in which case, where is the point?
