Well, that is arguable, an arming sword is meant to be used in conjunction with a large shield, which is a much simpler though not necessarily inferior style to the kind of sword and buckler / sword and dagger methods used with the Sidesword. (Long held RPG tradition notwithstanding, Longswords are two handed weapons and their use is extremely sophisticated...) If you think sidesword is simple you should try studying some Marozzo some time...
Oh no no, I wasn't implying that sidesword is simple. Not at all. But neither are the rapier, two-hander, or many of the others classified as "martial weapons." I would say their training times are about equivalent.
I know D&D longsword is a different beast than the historical longsword

But, a rapier is definately a more specialized weapon than a sidesword, and we don't want to go backward. IN that case, I return to my first suggestion: the msallsword. Smallswords are even more specialized thrusting weapons than rapiers are. IMO, both rapiers and Smallswords should require advanced training (expertise), they are both far more difficult to learn to use effectively than say, a cutlass or a mace, and since both are civilian weapons, their use would not necessarily be training for the typical soldier or even knight.
I wouldn't say the sidesword is "backward" from the rapier. It continued to serve in warfare when the rapier took the lead in civilian defense.
Anyway I agree that the sidesword and smallsword are not really replicated by any current D&D statistics, but neither really fits the description of the thinblade as put forth by WotC in Dragon magazine or the Complete Warrior.
If I had to take a guess, maybe the thinblade is something related to the estoc. Here is a description from the Wikipedia:
"As armor improved, so did the methods of attacking the armor. It was quickly realized that cutting weapons were losing their effectiveness, so crushing weapons such as maces and axes were utilized. But thrusting weapons that could split the rings of mail, or find the joints and crevices of plate, were employed. Thus was the Estoc developed. Estoc is French, meaning thrust or point. Tuck is the English version of the word. Many consider the Tuck a forerunner of the rapier, but more likely it is a merging of the civilian sword (Espada Ropera) with the effective, and lighter tuck, that produced the rapier. But the tuck was an effective weapon. The long, straight blade, very rigid could be thrust with one hand, or the second hand could be used to grip the blade to deliver an even more powerful thrust."
This seems to fit well with the rulebook texts.
