Switch Axe is the true master weapon of MH, one of us, one of us.
Yeeeeeesssss.
That said, I am actually trying to use other weapons now, because I've used the Switch Axe exclusively all the way through the game (I used the SA almost all the time in MH3 and MH3U as well). A big incentive to make the switch (hurr) is the fact that SA aren't often available in the Arena - and I'd really like to earn that Felyne Hairband X that gives +13 Charmer.
I've been attempting to use the Charge Blade...but funnily enough, it actually feels very clunky to me compared to the SA. I think I'm so used to rolling and sidestepping with the SA that it's second nature to me now.
