It definitely has a lot of tiny bits which will require a lot of patience. Destroids are pretty easy and so far, guardians are okay. I'm working on the arms at the moment and hopefully will be done building the box set by this weekend. You are doing pretty well for your building time, so don't get discouraged!
Guardian took the longest for me. Tried setting up their two arm grip a couple of times, but gave up after several tries. Also while you can't swap upper arms as easily between the guardian and battloid, I did swipe the pointing finger from the latter's sprue to give a few more variations for the former.
As a long time assembler of models (25+ years, but mostly GW stuff) I would have to agree with some of the other posters by stating that the modeling aspect of this game is not for novices. I also worry about the long term viability of this game if the modeling aspect continues to be such a huge barrier to new players.
If they can't build the models and get frustrated, they won't play.
