I havent played 40k in almost a decade and I am looking to break back in with an army that is strong, flexible, and isnt covered in cheese like eldar/tau/necros seem to be these days, while also not being as common as space marines. I made up this list and want to see if there are any glaring holes in the list, or if it seems like it can handle most common armies decently well.

HQ: Pask in Vanquisher w/ Lascannon, Heavy Stubber, Camo, Relic Plating
Pasks Friend in Exterminator w/ HB sponsons, Hull Mounted HB, Heavy Stubber, Camo, Relic Plating

Troops:
PCS #1 w/ Autocannon Vox
PCS #2 w/ Lascannon Vox

Infantry Squad #1 x30 w/ Commisar, Primaris Lvl 2, 3x Autocannon, 3x Flamer, 1x Vox

Infantry Squad #2 x30 w/ Commisar, Primaris Lvl 2, 3x Lascannon, 3x Flamer, 1x Vox

Conscripts x50 w/ Priest

Heavy Support:
LR Exterminators x2 w/ Multi-Melta Sponsons, Hull HB, Heavy Stubber, Relic, Dozer, Recovery Gear, Extra Armor

Wyvern x1

Wyvern x1

My general deployment will be Pask and his buddy deployed in the rear covering the Wyverns from enemy LOS, and bubble wrapping all of them with the 2 guardsmen blobs with flamers and autocannons/lascannons. The extra Exterminator squad will advance either behind or on one of the flanks of the conscript squad.

I figure the exterminators can handle most flyers and MCs just by the sheer weight of dice, Pask and the 5 Lascannons can handle all high AV units and can reliably get a few kills if there is no heavy armor around to shoot, the conscripts can tarpit enemy assault units advancing across the field, and the wyverns can mulch medium and light infantry, along with the autocannons from the other 30 man squad. All of the autocannons, lascannons, and executioners can reliably handle flyers quickly.
