Had a quick look and hadn't noticed anyone raising this previously.
I have a slight issue with the up/down percentage figure included with the dice stats. Long term, everyone's % is zero. I understand that over a longer period it's much harder to maintain good or bad (despite many player's assertions to the contrary) luck, but the % figure means nothing. I think it would be better to use a value based on the standard deviation (positive or negative), or placing it in a percentile (different to %) of say between 1 and 100, thereby giving a more accurate idea of luck.
At present the % figure is the same if you area 0-2, or 0-202, yet there's clearly a huge difference in terms of luck between the two. I understand where the figure comes from, the attacker in a 3v2 has about a 55% chance of winning each battle, so the result comes from taking the current percentage (0% in both the above) minus the expected (55%), would be -55%. Whereas a standard deviation or percentile would give a truer reflection of the status.
Be good to hear what others think.
