I feel I ought to elaborate on the custom equipment I discussed earlier in this thread a while ago now...
For those curious, my initial equipment was a Super Agility Badge with +35 Speed and -22 Attack, a Mystical Magic Stone with +31 Attack and -21 Defense, and a Protection Badge with +15 Defense and -7 Speed. My numbers in total being Attack 9+, Defense -6, and Speed +28. This set gave me AC SH dairs easily and it was with just a small set of options as I'd not acquired much equipment at all at the time. I did some tests on my power and defense as well with Warlock Punch from the default position of FD. I could kill default Ganon about 5% earlier, but he could kill me about 4% earlier. The damage he did to me and the damage I did to him were also increased in both cases.
Later I got more equipment and was able to make a custom Ganon with Attack +2, Defense +1, and Speed +22. Still had SH AC dairs and no negatives. Yes, I didn't hit as hard, but default Ganon hits plenty hard already. I didn't test if the 2% gave a significant boost to my attack but I'd imagine it wouldn't be more than a 1% damage increase or a 1% sooner kill.
I understand this stuff may not at all be relevant to competitive play since I'm talking about custom equipment here, but I did acknowledge that in my previous post. Just elaborating on my customs for those curious.
