You shouldn't be booosting unless you don't have haste/ marches.
Ever since footwork was released I've used it for fast TP gain which is actually useful, for instance to stun lock a mob (remember porrogo madames ? Ultima etc ), and also to farm WS-proc'ed mobs in dynamis (as there are always non-magic and non-JA mobs at camps). For instance in dynamis since the goal is to spam WS on those mobs, I pop defender footwork, and I can do ~10 weak ws per mob before it's dead vs one victory smite or 3-4 normal ws (with naked H2H). I think it would be interesting to boost footwork in the optic of "faster TP gain" even if it means "lower ws damage" since you could use it to proc mobs or stun lock mobs. Also procing seems to be something they plan to introduce in every endgame, so it can only be a good thing.
