That's cool, but it's also like...one CB Axe swing and resource-dependent. But it's cool that it's in and I want to get better at using it
So, I know that for Switch Axe the application is a sort of "evasive attack" from Wild Swing combo, and with Lance, you can basically turn yourself into a shielded turret, but I'm not familiar with Charge Blade so I had to go and "lab it" in training area, since I'm also curious of the nitty gritty.
If none of this is new to you with CB slinger burst, then your guess for ideal use is as good as mine:
1) The slinger burst, and following Dash Slam, or Elemental Discharge II, can seemingly be targeted in any direction regardless of the move that came before. It seems to be by far the fastest way to turn up to 180 degrees in axe mode and attack accurately in the new direction.
2) Most monster-dropped slinger ammo are guaranteed flinches, and even stone/redpit have
some chance to flinch since those have KO damage (better with impact phial setup?). So in axe mode, when dealing with a particularly agile or raging monster and you have the monster ammo, you can attack -> slinger burst flinch -> dash slam/ed2 -> slinger burst flinch -> dash slam/ed2 -> slinger burst flinch -> dash slam/ed2
3) This is a combination of the previous two points. There are a lot of monsters who do repeated charge attacks or otherwise hop around (diablos, tigrex, rathian, odogaron, etc.), and the 360 degree flinch on demand from monster ammo can sometimes protect you in your less mobile state better than a dodge might.
