I dont get why you have allied the Eldar....

Well, hoping for something usfull on farseer, he van run with incubi or grotesques

Ya, not really feeling the allied CAD. A single ML2 psyker really wont add much to a 2k list. You are also quite light on AT. May be worth freeing up some points for scourges/reavers for some AT (or if you are using allies, some CWE firedragons/wraithguard/etc)
