You are probably right. If it was user error then that falls on Giant as it was a brand new bike. I know I had replaced the inner cable twice, and pulling on the cable it was nice and smooth. I had a spare 105 rear derailleur so I installed that which didn't help. I work by a different shop so I had them align the rear derailleur hanger but that didn't solve it either. So i went back to the LBS I bought it from so they could figure it out. Took them a while lol. Only after replacing the housing did the issue go away.
