I'd like to use pathfinder for my next Eberron game. However, while I can give changelings and kalashar a pass, I really like warforged and want to keep them as an option for my players. How can I upgrade warforged to be on par with the other pathfinder races?
My current approach to this would be to use gearforged rules, from Kobold Quarterly (Issue 16, Winter 2011, Ecology of the Gearforged, pg 13), with warforged flavour text, but they have some oddities like no constitution score. Additionally they seem kind of underpowered, as they trade only getting minimum damage on healing spells for a list of immunities, and get no ability score bonuses, whereas other races get +2 net. Also, it seems like they would make bad fighters with no constitution score and thus no bonus HP, which is what Warforged are supposed to be about, thus probably making them a bad fit.
The only major change between most of the pathfinder races and the 3.5 handbook ones is the stat effects, would changing the warforged from net -2 to net 0 be good enough to adapt the Warforged from the Eberron core book to Pathfinder? Or should I got with +2 to any one ability, like they did with Half-Orcs? Or should I stick with the KQ Gearforged? Should I give THEM a stat bonus?
