Deploy at two sides of the table so he has to split up. Then use your superior range to shoot everything at one of the splitted parts and move out of the way of the other. If he doesn't split just move away and shoot at whatever you want. Concentrate on the fast and the very shooty stuff first, and don't be afraid to move away somehting that is threatened, even if you loose a bit of shooting, you should be fine.
Thanks for the suggestion. I will definately consider splitting my army, but it really depends how deployment goes and how the table is set up.
I was planning on hopefully keeping as many battlesuits in reserve as possible and then deepstriking them to where a Mawloc would burrow. If he got the Deathleaper, I would use them to take him out, which would be fairly easy, so that he does't get an automatic hit with his Mawlocs.
