Since Urist was here, I hope he would have a look here again.
What I want you guys to pay attention to is the new balance between hand-and-a-half swords, or, I should say, the balance between their price-to-value ratio (considering the weapon upkeep prices). Pre-patch longsword (the best 1 1/2 sword) was, methinks, 6 points longer than a bastard sword, had better cut (37 vs 35) and thrust (I don't remember exactly, but I think there was a 2-point difference too). Price did not matter much, since both weapons were affordable. That made longsword, on par with an uber-spamming katana, a very popular choice for fighting.
Now the weapon stats were modified:
Bastard Sword 1886
weight 1.8
requirement 9
spd rtng 99
weapon length 101
swing damage 35, cut
thrust damage 23 pierce
Secondary Mode
Heavy Bastard Sword 4200
weight 2
requirement 9
spd rtng 98
weapon length 105
swing damage 36, cut
thrust damage 24 pierce
Secondary Mode
Longsword 5123
weight 1.8
requirement 9
spd rtng 98
weapon length 106
swing damage 36, cut
thrust damage 25 pierce
Secondary Mode
So, currently, the only significant advantage of a longsword is its length. Still, 5 cm is not that much of a difference. I'm not speaking about nerfed stab here, this is quite a different story. However, I don't understand the reasoning why the thrust using a two-hand grip and a thrusting blade (such as a bastard sword or a longsword) should be weaker than using only one hand and a thrusting blade (such as in-game long schiavona or an arming sword). But that's the topic for a separate thread.
It is the upkeed price that makes the longsword completely useless as compared to the bastard sword. Indeed, the price of the longsword is 2.7 times higher than that of a bastard sword, while both weapons have very similar characteristics. The heavy bastard sword 20% more expensive than a longsword while having the same stats.
IMHO, considering the price-to-value ratio, bastard sword is the only viable choice among all hand-and-a-half swords at this moment. Wielding a heavy bastard sword or a longsword just makes no sense, since you have to pay MUCH more for a negligible improvement in stats.
