Steps:
1. Activate Boost.
2. Use a weaponskill.
3. See no change in damage compared to a WS without Boost.

Tested this with H2H, club, dagger and staff, using MNK/BLM, BLM/MNK, and THF/MNK. Lack of damage increase results are the same across the board.
All of the other adjustments appear to be working as per the update announcement notes.

Can confirm, no bonus damage is being added to WS
