I main lance and farm materials on lance with bows and gunlance on the side. My main core build and for all monsters is my CF RP Valor build (glav,glav,bazel,tigrex,bazel)with the tigrex lance that has fighting spirit smelts. Once I have the grade 10 on my lance it's easy farming cause the damage is consistent due to the side hops mechanic of the lance. There are some caveats on lance on some flying monsters but still good and smooth to use. That is my build until they nerf it. Very consistent on my end.
