Two Sets of Rules, the Good and Bad?

[Sorinth]

I assume this was a joke answer because you missed the question by removing the context.

Why do creatures have Legendary Actions? Are they quicker? Or did the authors just need to rebalance the action economy?

The metagame bodge breaks verisimilitude for me. I would rather have legendary creatures rather than an ugly bodge.

Is the Dex 8 Fighter with Action Surge and 4 attacks per round quicker then the Dex 20 Ranger with his measly 2 attacks per round?
