@Mr_X: I agree, I've made the same mistake over and over again in fighting multiple enemies, that is going for the strongest player and killing him fast so to quickly get the upper hand. The result is, of course, that I will fight against a greater number a lot longer, instead of taking them on from the other end of the scale. You need space and focus to take down the best of them, so always target the low armored/inexperienced opponent first. Reducing the number of enemies is a priority, because it narrows your focus.
Usually I see 2 takes on how to fight multiple people. 1) go inbetween them, swing wildly and get them to attack eachother, create confusion and 2) try to keep only 1 person in front of you, keep backtracking, use the closest as a shield from the rest. The first one is a game of chance, imo, and the second is so hard to pull off, because every one of them will try to flank you!
I'm messing with the idea to combine the two by adopting the 2nd stance and quickly at the right moment pass between them and take the fight to the other end of the small pack. Risky, but let's face it, the more time you spend backing away from them, the more time they have to surround you properly. You can't back away as fast as they approach. At one point or another you will have to "get out", so it's better to choose this very time yourself when the situation favours you. Haven't gotten it to work the way I want it yet, though!
