The problem with parsers is that it's always assumed that the numbers supplied by them are significant differences without much consideration other than for "power leveling" and DPS, while this game is designed so that there is little permanence thus far promoting almost everything as a viable means of play. The unintended effect of such things is to stigmatize the game community by having players try to sect themselves as "hardcores".

However, this bound to happen no matter what- so it has no harm for simple calculation's sake, though I certainly hope SquEnix is investing in such for their own testing to tweak and adjust things as needed to make a broad scope of value with no "best" in sight.

Point is- Though it's bad for a game community, it's an inevitability, legal or not. Thus, it's probably best for SquEnix that they let the players do the hard-testing for them and make all the calculations they want.
