It's not a big deal but it is a complaint. On the Yamato, just like on the Hi-Metal, I usually just leave the intake covers on. But because the Hi-Metal requires you to swap the heat shield I always have to go get the heat shield or canopy when I want to switch between Fighter and Battroid. It's a bit of an inconvenience which the Yamato doesn't have. It would even be better if the heat shield just covered the canopy, instead of having to take off the canopy then put on the heat shield. But, it's a minor complaint. Like I said the Hi-Metal has the overall easier transformation. But that one thing is a bit more convenient on the Yamato.
