For my wind archer, I jumped through training grounds rather quickly (and never getting less than 70% per hour)
By 60, I had already moved to wind raiders, you can either go to lower ascent, or if that is filled, go to thunder corridor (or is it tornado? I could never get the name right). MSEA doesn't have crimsonwood, and these places are god send for training =)
I went arrow rain first, since it's a mob skill and EVEN if it's just as strong as storm break, it's range is larger and works wonders at typhons (which you can start going there at level 73~75, but will be burn thru pots) But if you did get the wind piercing instead, just add some puppet and after gathering them up, use puppet, and start firing away.
Of course you can try himes at those levels as well, since both typhons and himes give the same amount of xp, but himes do a lot more damage (1.6k roughly)
