It looks like you have a lot of confliction in your list. For example, you have a Demolisher witth sponsons. It has a short range and needs to be moving toward the enemy the whole time. I would put the sponsons on the
LRBT instead, because with its greater range it can sit in the same place and shoot all of its guns. The veterans really need a transport, they are too expensive and squishy to be left in the open, if you're going that route you'd be better off with more blob guardsmen. On the same note, I wouldn't add a heavy weapon to your vets, because they are generally going to be the more mobile force of your army. If you drop the lascannon you're about halfway to a chimera, and only need to find 35 pts somewhere else for it. I would drop the power weapon from your
CCS, because they should never really be in combat. The 4 flamers are a great idea though, because they can toast anyone that gets too close to your blob. Speaking of your blob, I like what you did with it. The
GL AC combo works wonders in my book. However, you only gave your commie a
PW. I would either go all out (Commie and Sgts with it) or no
PW s at all in the squad. I would say lose the Stomtroopers - they're basically like more expensive veterans and a point sink in this Codex really. Finally, you may want to ditch the sentinel. I'm not saying they're bad, but you can't take one alone. It's not redundant enough to be a threat. Again, all in or not at all.
These are just my opinions and experiences though, and I do not discourage you from playing your own list and being creative! Experiment, what you find may surprise you!
Bottom line though - specialize more, and trim the fat. Lose the Lascannon, Stormtroopers, Sentinel, and Power Weapons. You should have enough points for a Chimera for your vets and maybe one or two of your command squads. Alternatively, you could spend the points on more
PW s for your blob, more sentinels (2 or 3 can do pretty well in a 1K game), or just flat out more guardsmens!
I hope that helped at least some
