Calculating a monster's 'score'

Pretty interesting question. To do it right you would have to score per map not monster. Also it would differ from job to job and per lvl. How to calculate: Grind for 10~15 minutes at the map with a certain job of a certain lvl (with clean class equips nearest to lvl), maybe do more than one rotation too -> Look at % increase. Tadaa thats your score =) Now repeat for every map, job and lvl. GO!

PS: Only looking at the numbers: Just exp / HP is allready good, maybe somehow calculating their def in it but I don't know how that works. Then maybe multipy that with mobs / area like fiel aid (not the inverse though since it should have higher score if better to be a score :3). Then maybe add some multipliers for certain jobs, example ice meak = *1,5 for icemages etc.

That would be too tedious.

I have one way. We calculate a component score from each stat, e.g EXP/HP, EXP/PAD, EXP/PDD, etc, and the lowest score is taken as the monster's score.

Obviously, for the PAD/PDD/etc we'd have to do something more complicated than a simple EXP per PAD, since that doesn't really make sense.

Perhaps use the stats to affect the HP instead? Since higher defense effectively equates to 'higher' HP.
