I have an interesting situation here. I am trying to salvage an old character. She is currently fighter7/rogue1 and has TWF. I plan on taking 6 lvls of ranger for tempest, but I dont want to double up on the TWF feat (took it at lvl 6 way back before tempest). So my question is this. Will I be able to take ITWF next level and be able to swap out the TWF feat I took at 6 some time after my second ranger level when i get that feat for free? Does that make sense?
