At 65 base speed, Scizor rarely runs a speed nature, and never runs max speed EVs. If the rare trainer really wanted to run a Choice Scarf Scizor, he could make it hit whatever certain (non-standard) speed he wanted before the Scarf. It would never be a target (at 376 speed) that other trainers would want to overcome to avoid in the standard metagame.
(Though, 376 outruns a surprising amount of stuff... nice surprise there!)
If it becomes common, I'd add it.
I reccommend putting this into logarithmic tiers like Dragon Tamer did in the Max HP * Def thread. That would help remove the endlessness this might look like.
If you could teach me what a logarithmic tier is, I'd be happy to look into it. T_T
It also gives reasonable groupings, not arbitrary human ones.
Actually, the tiers are based exactly on the very strong tiers that were created in Advance generation. 299 was the old breaking point for a ton of pokes, because everything at or below it was perfectly content to be outsped by the "fast" pokes, and almost always ran a non-boosting nature. But everything above it didn't want to be outrun by slower pokes or their fast brethren, and so almost always ran a boosting nature and max speed to be above them.
Garchomp sort of shatters this wall in D/P - you could even call him his own tier, maybe. But the rest of the tiers are still highly intact.
I would venture there's very little arbitrariness to where they are defined.
Do these:
- 538 - CS 252 Aerodactyl (130)
- 523 - CS 252 Weavile (125)
- 478 - CS 252 Gengar, Tauros, Espeon (110)
have a nature boosting speed also??
If you look more carefully, the legend below the list will tell you
CS means a pokemon has a Choice Scarf, and
252 means a pokemon has 252 speed EVs and no boosting nature.
Pokemon rarely run boosting natures and choice scarf, as the ones that bother to use scarf are often fast enough to outrun everything important anyway without the nature.
and how about
475 - Motor Drive +nature/252 Electivire (95)
with a choice scarf?
You would never need to list a motor-boosted Electivire
with a choice scarf, because firstly, the scarf would destroy Electivire's ability to sweep once it caught a speed boost; secondly, because it's so outrageously fast it's nothing you could ever plan for, even if some crazy fool decided to use one on their team as a funny gimmick.
