Heeya Wego, managed with my ninja skills to read about a post you made about 100% Dark rattata xD
Have to say that it doesn't really matter that it gets x4 fighting weakness, you ever saw the regular raticate not get killed by a fighting move? yeah me neither, it to frail so it doesn't matter xD.
Its a good thing now that it gets dark because it gets Stab on Sucker punch which makes the general Guts set better.
But of course the boost of this matter is rather mehish but it does make Raticate a better pokemon though.
Just wanted to share my thoughts xD How have you been friend?
