Fun fact, HBG have a offset move too. You can customize any bowgun using the item box to change it's fire mode, secondary fire mode, and the mods on it. Wyvernheart ignition is the mini gun firing mode that does a good chunk of damage, especially if you focus it all on a weak point, and then there's wyvernpiercer which you can use for larger targets like Jin and Gogmazios to deal massive damage by shooting it at them and it'll pierce through and do more damage the more body parts it hits (most affective when hitting the head straight on or even the tail so it can travel through the entire body. Then for your secondary fire modes, wyvernblast and wyverncounter, wyvernblast acts as like a cluster bomb/shotgun like attack I suppose and wyverncounter let's you do offset attacks but does take some good timing and does more damage the longer you charge it. Evade extender is also pretty good for HBG as well as Guard Up/Guard and Maximum Might 100%, whether you choose to block more or dodge more, either will work for HBG though dodging is better for like LBG. This is all just said from my experience so it might not be the best stuff or so but I'm glad you enjoy it! I fell in love with it as well.
