Wow, imagine how many points the Warforged must be in this system!
Well, aside from the "numerical values of holistic abilities cannot be really measured accurately in a vacuum" BS that we always hear, and that I believe is really true, yeah, a Dwarf Cleric is officially the twinkiest thing you could ever play.
But you know, I haven't seen one yet. This is primarily a difference in perception vs. play. Which, oldy enough, is the same way one defends the Warforged.

Yes, Clerics seem like the most powerful class, and yes Dwarves get more goodies than most other races. But it certainly doesn't unbalance anything, as far as I can see...it's not like dwarves dominate any field, or that they are somehow dominating and lording it over every other character...it's not like one party with a dwarven fighter and a human fighter would always have the human being frustrated, and the dwarf beign successful, given the usual array of challenges. Just like when given the choice between a human cleric and a human fighter the choice isn't always obvious. It's not like they're overpoweringly mighty, overshadowing every other race, and they're still probably the least-played race in my games. Not for lack of trying, either, the dwarves I've had in the game have all been quite hardcore (no comic relief Gimlis here!).
As for half-elves and half-orcs, bah. Who needs 'em, when I allow full elves and full orcs?
So, you're right, they do get a lot of goodies. But it's not enough to make other race choices useless or invalid in the game by comparison, so they remain tentatively okay. And the reason I personally ban the Warforged is because I think they do overshadow the dwarf in many areas, to the point where a Warforged Fighter and a Dwarf Fighter would mostly have the warforged shining in the majority of circumstances (not all of 'em, but enough to be nervous about.

)
