While I agree that Eldar are now better than before and we should mostly be happy by the changes... pretty much everything you have said here is complete crap and doesn't validate the point at all.
There are good things to say against those who suggest that Eldar really, really suck, but these are none of them.
1. It IS a bigger deal for Eldar to have their powers stopped, as Eldar rely far, far more upon psychic powers than any other army. No, no, Grey Knights do not, Grey Knights do fine even without the powers, the powers are just a boost.
2. Wraithguard have always been good, but until they make a plastic kit, they're far too expensive.
3. Pathfinders are still stupidly over-priced.
4. Yes, yes it is stupid that the Eldar have crappy flyers compared to the Imperium when they're meant to be awesome in the air. This is simple fact which is undeniable.
I play multiple armies, and Eldar are just one of them. Yes, Eldar are still decent. The negative points that have been made about them, however, are still true and valid, and although they are usable, there are a lot of options which are terrible. Just because you can make a good army with them, doesn't mean they're good, as people want to play with the models they like, rather than the ones they have to use to make a decent list. So kindly stop being an obnoxious moron and actually consider what is being said and reply in a decent manner rather than coming across as a fool.
