I started asking question in the Q/A part of the forum, but t'was in an already existing thread, can be confusing, plus I have other questions, so I'll just start a new thred here with all the questions in one place

_ What feats are necessary/useful for Dual Wielding? (I'm a bit confused by the wiki and the builds proposed) ... Like do you need the "two weapon fighting" feat? Or does the "Improved two Weapon fighting" feat provided by the Ranger class cover it?
_ Is "Call of the Wild" worth on a Ranger with 16 or 18 base CON but not full ranger lvls (23-27 lvls ~)?
Thanks in advance!
