Well, on foot 1vsMany was always a hard thing to do in M&B, I'd say Warband was bit easier on that since enemies tend to go 1vs1 more, but you got mobbed all the same when they got together. Once you had good skills and armor, it was easier to do so. Here, it's kinda the same, 2H with high skills lets you murder a group solo too, but it always needs high athletics to outrun them, 100 at least from my experience, with all perks for speed, before that it's best to use javelins to gain the athletics xp and cull their numbers to something manageable. It's fine line between hero/realism that was in WB, here it's more toward realism (not a good choice in my opinion, but it is how it is).
