A speed of 1.0 is not middle speed, it is slow speed, and most vanilla weapons have consistent speed within a class (dagger, shortsword). Despite this many, many TD weapons have 1.0 as a speed, making them terrible.

Weapons with abnormal speed for class
Axes: T_Nor_Ancient_WarAxe_01, T_Ayl_Regular_WarAxe_01, T_Cr_Goblin_Axe_01*, T_Com_Farm_Hatchet_01*, T_Nor_Orn_WarAxe_01
One Hand Blunt: T_Dwe_Regular_Club_01, T_Cr_Goblin_Club_01, T_Bre_Mithril_Mace_01, T_Orc_Regular_Mace_01, T_Com_Wood_Mace_01*
Staves (these are particularlly noticible as high speed+reach is the entire point of staves): T_Dwe_Regular_Staff_01, T_Nor_Orn_Staff_01, T_Orc_Regular_Staff_01
Long blades: T_Orc_Regular_Longsword_01, T_De_6th_Longsword_01, T_Imp_Reman_Broadsword_01, T_Com_DaedSteel_Broadsword_01   
LOng blade 2h: T_Bre_Mithril_Claymore_01, T_De_6th_Sickle_01, T_Dae_Regular_GSword_01, T_Com_DaedSteel_Claymore_01
        Short blade: T_De_Aena_Sickle_01, T_Com_Var_Cleaver_01, T_Com_Var_Knife_01/2/3, T_Com_Farm_Trovel_01 (may be deliberate as it's not really a weapon), T_Imp_Legion_Shortsword_01, T_Imp_Barrow_Sword_01,   T_Ayl_Regular_ShortBlade_01, T_Com_Adamant_Dagger_01, T_Bre_Mithril_Dagger_01, T_Com_DaedSteel_Dagger_01, T_Com_Gold_Dagger_01 (this last one should actually keep it's lower speed and gain a higher weight, like the acompanying Danswyrm Silver Dagger)  
(* indicates a weapon I think should actually be raised to be faster than normal for its class rather than merely match them)

The following may be deliberately off in speed as part of a conscious attempt to balance better power and shouldn't be overwritten.
T_Nor_Ancient_BattleAxe_01, T_Nor_Orn_BattleAxe_01, T_Com_Iron_GreatMace_01, and all seax (these have noticibly higher power to compensate for their lower speed),

The following are too fast
T_Imp_Legion_Longsword_01 (fast as a shortsword), T_Nor_Ancient_Seax_01 (stated like normal shortsword, not seax)

On a related note: Wooden Crossbow's damage range brakes conventions for crossbow damage and is abnormally expensive for its damage. Give is 10-10 damage and a value of 60 or 70.
