Warforged, to me, are just a dumb, tasteless idea. Fantasy robots who aren't golems. The idea is a non-starter.
I don't like Eberron either, and am glad it has set off into the sunset. I understand that it won the setting competition because it echoed ideas put forward by a lot of other competitors, so WOTC thought it would be popular. Big mistake. A lot of people trying to be original in fantasy come up with the same bad ideas.
Stray too far from mythology in fantasy and you pay the price.
(It has something to do with our souls, if you even believe such things exist, thus the extreme popularity of the fantasy genre. People with souls like fantasy without exception, which is probably good news for you if you're reading this, because it means you'll come back. After death, you'll spend approximately three unhappy years spent in a quantum state called Summerland, and bam, you're back in another body, possessing a foetus by merging with a conciousness similar to that of your soul, which is a mindless artificial conciousness process as old as the universe itself and that deals solely in tendencies and emotions. Yes, D&D actually has a very strong connection with the occult. The D&D occult scare back in the 80s was actually far from baseless.)
Campaign setting-wise, I believe everyone should play Thunder Rift. It has everything D&D needs in a microcosm small enough to detail and get to know, and sticks to the rich vein of Tolkienesque mythology.
