The silver dragon option for Dragon Form seems to be missing an attack. It is not comparable to the gold, blue or red dragons, which have 4 attacks each.
It is generally hard to read the spell description because it is so dense. Why not simplify the whole spell to just one basic Dragon Form. While the different dragon types have traditionally scaled differently as monsters, it makes less sense to do so with a Form spell. The entry would be a lot easier to read if it just listed a standard set of basic melee attacks and their damage (bite, claw, wing, tail), standard breath weapon damage, and then included a shorter, separate list of each dragon color type which include its unique movement feature and breath weapon type. Varying damage based on color makes less sense with the Dragon Form spell. Some of the variance between metallic and chromatic dragons in the MM is traditionally based on the the fact that the metallics have a second option for their breath weapons. Versatility vs damage. But the Dragon Form spell does not offer such versatility, so why list 10 different damage options?
