yah what would be the best class to use for gianting?

dual sword blader
with a buffer/healer would be perfect

sword = better speed, not much but steal
Swords normally have Crit add on/speed (as for the rare ones you know)

A strength Bill poster is also really good.

But a dual blade is more common

i make the same dmg as a 2 sword blade...
as a billposter ~~

in my opinion a Billposter wir around 30 CR and 100% a speed or a blade wih axes :) and buffs
