it does make a difference but what he was trying to say is you can gain 10 di in other ways and save 100 pts.
you can add bushido and gain more then 10 di plus the 50 HCI with LS.
axes swing slow enough that you can LS every hit with a few MR on your suit.
i have tested this tho, and for pvp axes aren't the best.
my pally bush swordsman has a 30 ssi 40 di ornate axe with hml and hsl with 151 stam for a swing speed of 1.50.
even then its not fast enough to disrupt mage casting and if i am against someone with a faster sword i get owned.
a 30 ssi ornate axe you cant hit 1.25 swing sweed
you need 35 ssi with 180 stam to hit 1.25 on the ornate axe.
unfortunately the slower the wep, the more rare it is to get the SSI mod from runics
i burned about 20 bronze and gold runics to get one axe that had 35 ssi but it had crappy mods..
