I ran an Eberron campaign for a group of PCs including a human artificer, a human bard, a human paladin, a longtooth shifter ranger and a warforged fighter (later fighter/barbarian) with Adamantine Body. The warforged made an effective front-liner and I was able to rely on his immunity to paralysis to use some creatures that I would otherwise hesitate to send against a low-level party (some ghouls and a carrion crawler).
The warforged was a strong defensive character, but the shifter was more effective at dealing damage. This was partly because the party's main low-level offensive booster, enlarge person, would not work on warforged.
As a DM, I planned my game around the reasonable (or so I thought) assumption that the warforged's immunities would enable him to keep fighting (and drawing enemy attacks) even if the rest of the party was incapacitated. This did not work out during an encounter with dretches. The warforged was immune to the nausea caused by the dretches' stinking clouds, but failed a save against scare. This created several tense rounds of combat because the rest of the party was nauseated and could only stumble around as the dretches attacked, while the warforged was running away in fear. Eventually, the warforged returned to the fight, the rest of the party recovered from nausea, and together they squished the dretches.
Overall verdict: warforged are balanced.
