I made a post about it already, and this guy just made another post saying the same thing, and now you're saying the same thing, it's on the front page of the feedback section, it's a useful forum, you should check it out sometime.
There once was a tiger striped cat. This cat died a million deaths and was reborn a million times and was owned by various people who he didn't care for. The cat wasn't afraid to die... One day, the cat was a free cat, a stray cat. He met a white female cat, and the two cats spent their days happily together. Years passed, and the white cat died of old age. The tiger striped cat cried a million times, and then died. It never came back to life.
I would say arrows stacking to 99 would be a more likely fix. Which actually might be better, really. We know the game supports stacks of 999, so that'd be the quickest and easiest fix for them to implement. If it makes you feel any better, though, arrows only stacked to 12 when FFXI first came out, and max inventory was 30. =X Rangers had fun in those days.... All 2 of them....
