Giving drow their (almost) natural spell resistance was a big step into fixing one of the worst races in DDO, however it still leaves them far far short of par compared to the other races, but at least they have something else to put on their splash screen besides "They're just that cool."
The biggest problem I've always had with drow is their complete lack of good enhancements, removing the drow SR enhancements (even though they were horrible) did nothing to help this issue. Its not rare for drow builds to have absolutely no racial enhancements short of the toughness line available to everyone, or the rapier line if they are melee rapier users.
My suggestion would be to at bare minimum add the ability for drow to choose whether their racial enhancements go into dex, cha, or int, but I would also like to see an enhancement line that improves spell penetration (giving them a nice niche in spellcasting to compete with WF and humans), and another melee centric line since the drows of eberron tend to be barbaric.
