Salalaruru (who's one of the primary ComReps on JPside) did not address that WS are not getting the announced benefits at all, only that the delay until your next auto attack sticks around even after consuming it is working as intended. The few player replies after that are trying to figure out what it's good for now since a 1min CD seems like something intended to be used regularly and the damage increase is nice but the delay after use seems unnecessary.
"Accepted Bugs" forum is actually just the first stage that submitted bug reports go through as long as they follow the template. ^^;; Since I followed the template with the two Boost related bug reports, they'll look into it but doesn't mean that it's been confirmed to be a bug just yet.
