There's a lot of things that the newer throwing lances have going against them that aren't covered in the public damage calculator in the beginner's forums, but my feeling is that throwing feels much softer vs cavalry/charging infantry in general.
I probably wouldn't mind any of the changes if the slot bug were fixed.
That being said, the main nerfs to throwing in general were:
1. Speed bonus change for ranged, which was probably done to nerf HA/HX/HT.
-Patch: 0.3.3.0
-Old Value: missile_damage_speed_power = 1.9 (whoops, typo)
-New Value: missile_damage_speed_power = 1.0
-Relevant formula: raw_damage *= math.pow(missile_damage_speed_power, speed_bonus)
-Much bigger deal for throwing than the others, since their base missile speed is much lower, so lower damage vs fast charging enemies, more damage vs retreating enemies.
-Ironically makes charging cavalry much harder to kill for ranged.
2. "Extra penetration" value changes (Larger soak, lower reduce)
-Patch: 0.3.3.0
-Old Value (Soak): 1.2
-New Value (Soak): 1.6
-Old Value (Reduction): 0.6
-New Value (Reduction) 0.5
-The calculator that everybody uses in the beginner's forums doesn't have extra penetration (pretty much all ranged weapons except stupid stuff like smoke bomb/ladders) factored into it.

Damage comparison without speed bonus:
Current 47p:
Raw Damage: ~80
Armor: 70
Minimum: 20.02
Real Average: 23.95
Maximum: 27.98
Current 60p:
Raw Damage: ~100
Armor: 70
Minimum: 32.04
Real Average: 36.8
Maximum: 41.69
Old soak/reduction with glorious old 60p
Raw Damage: ~100
Minimum: 36.01
Real Average: 40.39
Maximum: 44.89
(36.8 * 4) = 147
(23.95 * 6) = 143.7
(40.39 * 4) = 161.56
3. Recalculation of WPF penalties for ranged in general
#1 probably has the biggest effect for throwing weapons in general. The difference in killing thresholds seems too drastic vs heavy armors when you hit an enemy in the arms/shoulder since everyone in crpg flails around.
#2 probably has the biggest effect on cut throwing/cut arrows.
#3 probably has the biggest effect on trolly 3PT throwing dagger/war dart builds since they target squishy people/always try to headshot anyway.
