Hello, here is a small guide i made for your Abathur build if anyone want's to test it. It's not exactly what you asked for Illidan but i think it is worth a try. (BTW i am an Illidan player).

Here it the guide: http://www.heroesfire.com/hots/guide/abalidan-abathur-illidian-wombo-combo-4617

Thank you for the Abathur build by the way! It's very useful!
