help on mhw: iceborne

Hi, my English is bad, so I translated this message with Google.
I've been playing MHW for a short time now, and now I'm on :Iceborne, and the difficulty is skyrocketing.
I already have a good set, but I'm having trouble choosing a weapon. I use the axe-sword and bow. I use the Defender V version in both, but now, after facing the Howling Legiana, I feel like I'm hitting a wall, and it takes me a long time to defeat the monster.
Do you recommend I continue the same way, or is there a weapon that will speed up the experience?

Thank you so much
