It looks more like the HHs Attack Up S/L songs in G Rank are going to give bigger buffs, and HH will now do more KO damage.

For GL, it's talking about Shelling and Super Armor, so wether the effect of being shot as reduced effects for players now like they did with Hammer or they are mkaing them more powerful, if not both.
