I believe the impact/cutting versatility of lances was first introduced in MHF1. For the western players, that is. I reckon it actually started in MHG, but due to lacking information on that game I can't say for sure.

Also, from what I observed in mhfo, I am having doubts if lances actually do have this dual-type damage ability in there. Lances can break Daimyo Shells in mhf2/mhfu. Strangely, I wasn't able to break it in mhfo when lancing. And yes, I attack only the shell.

I'll give it another try later. I want to be sure about this one. Though it could also just be that in case of MHFO Daimyos the highest damage dealt to shell is done by cutting damage instead of impact (probably not lol), which causes the lance to deal cutting-damage there instead, preventing it from breaking.
