I never had any problems with the original Mako. Sometimes it was a pain in the ass, but generally it was fine. The customization option for the new one sounds awesome. Hopefully they will make the new Mako as meaningful as the ship was in AC4.
Considering I don't really participate in threads that discuss such topics and when I do I almost always say something dumb with zero value whatsoever, my perspective might be lackluster and/or flawed. When I said things look worse than before, I had the negative elements in mind and not the positive ones, so that could be responsible for that too.
