When I level my MNK during level 46~49 exp (at least 2 years ago, before ToAU exists) in G.C basement (triple-bats and beetles camp), I didn't see any Boost overwrite Bats Sonic Boom. I have Boost macro-ed and I use it very often stack with WS). And also, in my chat filter, I don't set it up to filter anything happen to the party, and I have a habit of scroll up the log window from time to time during parties. A few hours chaining bats (in different parties) and hit Boost at least once every battles, I did not see any indication of Boost overwrites Sonic Broom from the chat log or the Icons at the top of screen.
