At this point I'm convinced disk stat distribution isn't random, and it's some sort of pre-determined scam. Disks ALWAYS seem to follow a highly specific stat pattern when leveling them.
>CR/CD seem to get boosts the least (CD being the absolute least), followed by ATK% and AP
>flat "junk" stats seem to get boosts the most (e.g. flat PEN/ATK/DEF)
>the stats seem to favor distribution of +1 to each stat (seemingly each time a stat gains a boost, it becomes less and less likely for it to gain another boost)
>most common distributions seem to be +1 to each, +2 CR +1CD +1 junk if a disk has both CR/DR, etc
Has anyone kept a log of their disk leveling? Because There's no way in fuck this shit is just totally random. This isn't even going into how the base stats are distributed. I'm fairly sure "junk" stats appear far more often than desirable stats, both for main and sub-stats.
