Do we really need swarms/ mobs?
Of course not- but some of us find them fun. I sure do. And I think they're a great way to model "one man vs. an army" scenarios.
It's not a bad idea, but even of upwards of a dozen creatures, they already all share the same initiative count, and you're basically rolling 1d20 and adding a number around +5 to it.
You could resolve all 12 of those creatures turns in under a minute, even using miniatures (possible move, roll attack, turn ends, repeat).
Sure, but swarms are a way to make an encounter a bit different and, sometimes, more interesting.
