Imperial Guard List Thoughts: 2000pts

I've been out of town a lot lately for work which has kept me from making a proper post, but I've been making good progress on my Nurgle Army for WarGames Con-Team Tournament next month. Look for pictures this weekend!

After WarGames Con is over I plan on putting the Mantis Warriors aside for the rest of the year and instead concentrate of making my IG army competitive and (more importantly) fun to play with again. I had a lot of success with my IG back when the 5th edition codex came out, but eventually they became boring and difficult to win with against the speed to Blood Angels.

Below is a hybrid mech/swarm list I would like to try out. It has a lot of scoring units, with plenty of mobility and a couple of decent tar pit units (30 man blob squad w/ commissar and an Armored sentinel).  Normally my lists have a lot of outflanking units but this army takes the enemy straight on will hopefully hold out.


HQ

(120) Command HQ; plasma gun*4, plasma pistol

(55) Chimera

TROOPS

(50) Platoon Command; flamer*4
(55) Chimera

(110) Infantry Squad; power weapon, grenade launcher, commissar; power weapon

(65) Infantry Squad; power weapon, grenade launcher
(65) Infantry Squad; power weapon, grenade launcher

(55) Infantry Squad; flamer

(55) Chimera

(75) Heavy Weapon Squad; auto cannon*3

(90) Heavy Weapon Squad; missile launcher*3

(125) Veterans*10; plasma gun*3, plasma pistol

(125) Veterans*10; plasma gun*3, plasma pistol
(110) Veterans*10; melta*3, plasma pistol

(55) Chimera

FAST ATTACK

(100) Valkyrie

(100) Valkyrie
(80) Armored Sentinel; lascannon, camo netting

HEAVY SUPPORT

(170) Battle Tank; heavy bolter*3

(180) Demolisher Tank; las cannon

(160) Manticore

I know this list is pretty typical of IG with nothing too crazy but any thoughts would be helpful.
