Quick question. I'm new to CAP, and I've been noticing that quite a lot of analysis appear to be outdated, but my real question is:
Pyroak's analysis mentions Dragon Dance quite a bit, yet there is no DD analysis and it can't learn it Showdown. Was it's movepool changed to omit DD?
EDIT: On an SD Pyroak, is Max Speed really necessary to outspeed certain things, or is it better off running Max HP, considering its natural bulk and poor base speed?
Yes, the Pyroak analysis is indeed outdated. Originally it did not learn Dragon Dance, but then via revisions that were made to the early CAPs, its stats and movepool were changed to make it more of a physical sweeper. This added moves such as Dragon Dance to its set. However, since then, the CAPs were changed again to realign them with their original purposes, and thus, it went back to its original stats and movepool, being more of a tank than sweeper, and losing Dragon Dance in the process.
As you have noticed though, the Pyroak analysis, as well as some of the others, are out of date, as they references the additions that have since been reverted.
As for your speed question, Pyroak doesn't need Max Speed, but it can be useful. It lets you out-speed and easily beat uninvested guys like Scizor, Metagross, Vaporeon, and Skarmory. However, if you are not so worried about these guys, then there is no reason not to invest some in HP, as very few if any Pokemon with a lower speed stat will be running an EVs in Speed, meaning you don't lose out to much at all. Indeed, I am fairly certain that is outdated too, as the analysis references outspeeding base 110s, which is nowhere near possible with its current stats.
