So what would give this fits? Normally I'd worry about big bugs, but this has enough AP2 to take out the venom cannon and warp blast fairly quickly. Skimmers can be a problem, but there's still plenty of lascannons in the list. Drop pods might be rough, but with all this plasma I think I'd have a chance.
