>>22918518>No one uses Muscle Band or Wise Glasses for 10% power boost, so I can't see that being used either10% more power is entirely not comparable to being able to outspeed a bunch of Pokemon more 100% of the time. Speed is binary. If your Salamence is slower than your opponent's by one point, you get hit first and usually KO'd every single time.
An item that gives you only 2 extra points in speed would be much better than Muscle Band or Wise Glasses since that damage is negligible, outspeeding every non-choice scarfed Pokemon in your same speed stat is huge.
