no prob..first of all you want to get lots of rangers and pathfinders..for a 1000pt-1500pt game i probably would have four squads of 5 rangers and 2 squads of 4 pathfinders or sumthin like that...make sure they are all in cover
(because they get that incredible +1 added on to the cover save and the pf's get a +2). other than that, maybe reapers to truly make it a shooty army, and even a farseer to guide the reapers...also either get scorps or banshees; banshees if you face marines a lot, and scorps for anyone else; get a squad of 10 and put them in a wave serpent...basically IMO a well balanced alaitoc army should be very shooty, with some fast cc material...other than that you can modify it as you wish!!! hope this helps and good luck!!
