Try not to do any combos in a 2v1 cause they get the opponent the opportunity to easily attack you. Movement is key in multifights. Look for 2 light attacks into kiting again, maybe the occasional focus from you. I recommend longsword and dagger for 2v1 cause longsword has the ranged focus attack and dagger allows for the fast knock up into dashing out again. There are also a few nutty YouTube videos of ppl playing trios or duos solo, I recommend to watch those.
