[@VKAllen] In the past when i was either running a halo rp or in one and someone chose to use a katana they tended to either be one man army killing machines. 

And from an RP and lore perspective if there was a sangheili with an energy sword veruses a steel katana the sword would cut the katana like it was butter. And we are ODSTs fighting hand to hand with a sangheili the sangheili would win unless he were to get creative and not to mention shields it would only damage them a little and not taken out fully. Or a Brute chieftan with a gravity hammer, in Halo 3 ODST it took almost a whole squad in a cutscene to take out the cheiftan.

Those would be my points but again I shall leave it up to Thang.
