[MENTION=6748898]ad_hoc[/MENTION]: How do you keep finding these things? I've been looking and looking and refreshing and refreshing. Still nothing!
I like it a lot. And, AL depends on some elements of these, even for making your own, as you can only replicate a portion of a background that is official. This one introduced a new precedent in skill and tool choices. It's a pretty meaningful change.
Wow. Who wrote this?
People do understand that the flexibility isn't new, the rules say you can make any background you want by picking any two skills, a combination of any two languages or tool proficiencies, and picking any background feature and tweaking it slightly.
Heck if you don't use custom backgrounds than having two fixed rigid skill proficiencies is still flexible as if you gain a proficiency you already have from race or class you can again by the rules pick any skill proficiency you want. For example if you are a rogue who takes sleight of hand and stealth for class choices and then takes the urchin background you get to replace those two skill proficiencies with any two you want so for whatever reason you could take religion and arcana, and your second thieves tools proficiency becomes any other tool proficiency in the game.
Not that feats are remotely power-gamer-only. My players like feats because they like being able to customize their characters. Sure, they want to be able to do some cool stuff, mechanically, but they're not remotely power gamers/optimizers, and in fact often make substandard choices if it fits the character.
Let's not paint with too broad a brush.
