I came to think about this when contributing to the Generations wishlist thread... I don´t mind that there are various size classes, but I just find the present distribution of various characters into various classes a bit random. Now, that Swerve, other mini cars and the Insecticons goes into Legends is just fine, and that Classics Optimus and Jetfire are voyagers is fine, too. These characters are normally depicted as smaller and larger than the average Transformer, respectively. But Springer and Blitzwing? I don´t perceive them as being Optimus-tall, the only triple-changer that is usually depicted as bigger than usual is Broadside, who´s official update is yet to be seen... Especially for Generations Blitzwing, I find it weird that he towers over Classics Octane and Astrotrain. So I have two ideas for size class consistency, the first is just to stick to size depictions for characters in their robot modes in the cartoons and comics, let the average character be deluxe-sized and let the ones being shorter and taller than average get legends- and voyager-sized toys, respectively. Springer is Deluxe-sized, and Powerglide is Legends-sized (the latter is coming up, after all). The second ideas is to have a number of sub-lines for various kinds of vehicles, where the size classes for the toys is defined by the size of their vehicle modes and not from how their characters have been depicted in the cartoon (which in turn was based on the size differences between the original toys, at least for the original Autobots). In other words, Beachcomber would be really small (a beach buggy), Jazz and Cliffjumper would be equally sized (both are Porsches) and Huffer on par with Optimus size-wise (trucks). Inferno might be bigger than both of them (fire truck). What do you think?
