This conversation is like reading "tastes great! less filling!" commercial.
Here's the thing:
If you are a 100% pure bred optimizer, that extra +1 to hit makes the dwarf a no-brainer. Why? Because optimizing is about squeezing every drop of blood out of that stone. So yes, it's "just a +1", but hunting down these small bonuses and stacking them is what it's all about.
If you are not an optimizer (and personally I'd argue even if your just a 75% or less pure bred optimizer), this just doesn't matter. It never will and the difference will be as noticeable to you as I pointed out in my prior post in this thread.
These are two drastically different viewpoints that clearly are not seeing eye to eye. And at the end of the day (at the risk of repeating sentiments in my previous post), who cares? I'm not a 100% pure bred optimizer and I really don't care what an optimizer does in a game that doesn't include me. If said optimizer feels that they must play a dwarf warden to be optimized, why should it matter to me? On the flip side, if I were a 100% pure bred optimizer, I really wouldn't care what a non-optimizer did in a game that didn't include me.
I will concede that I don't see the fun in optimizing. The game certainly doesn't call for it (in my opinion, on many levels - its not a competition, it's collaborative; playing against type can be fun; the game is about role playing not roll playing; more options feels a lot cooler than limiting options). BUT, if that's what floats your boat - float away. It's not my place to tell you or anyone what is or isn't fun. But then that's kind of the point of fun - it's a personal thing.
In the meantime, it would be pretty awesome if folks would just say "yes a dwarf is a solid optimized choice but if you want to play something else you're not exactly gimping yourself"?
