Altered races in homebrew worlds

[Jeff the Green]

What are your thoughts on mechanically changing races for homebrewed campaign settings? If your DM said, no, elves are wimpy but wise and gave them -2 Strength +2 Wisdom, and similarly changed the other familiar races, how would you react?

If it was important to the world and didn't break anything I wouldn't care.

[Waddacku]

I approve of it.

I'm fine with it as long as things are told in advance. It can add to some nice changes of pace in characters and classes which you might not normally see due to previously "suboptimal" race-class choices.
