They do still have Lasguns, and they also count as 2 wounds per base. Personally I prefer Autocannon HWTs in my 30 man blob, or if I'm playing Vets in Chimeras I will put them there to shoot out of the firing hatch. It's nuts they only count as one model for shooting out of a Chimera. It really depends on what you're facing and what the rest of your army is though, if I didn't have so much anti tank coming from my tanks/fliers I would likely be more tempted to play Lascannon HWTs for the S9 AP2 of it all. Missile Launchers are also a fun time (Flakk being a waste of it), but again I still prefer the rate of fire and cheapness of the Autocannon.
