>>46209821The Choice items are NOT balanced, at least not as of Gen 4. When Choice Band was introduced, there very few competitively viable attacks with a BP higher than 80, and the ones that did exist had terrible distribution.
Then Gen 4 came along and gave everything access to high BP moves with minimal drawbacks.
Choice Band used to reward prediction, hence the name. Now, Choice Band/Specs are all about spamming your high-powered STAB and only occasionally using a coverage move.
