I hate mass shifting. Were it a part of the setting I wouldn't hate it as much but it's only there so the animators can have a bike be the same size as an SUV. Luckily in Prime is hasn't been QUITE as blatant. But I just realized that Airachnid is the same size as Arcee... A bot that turns into a motorcycle is the same size as one that transforms into a helicopter... Even a smaller helicopter like the ones Airachnids design is based on is still huge compared to a motorcycle. A motorcycle would be about as big as the cockpit +- 100%. I now will always think of that when I see them fight.
