Moving up to 2000pts

[gublyb]

Hey all some may remember some other posts I've been putting through as I've grown from a 500 to 1000pt army. You've all been incredibly helpful and it's made getting into warhammer really fun. I'm now at the state where I'm set to finally go up to a 2000pt army thanks to finding a second hand Tyranid army for purchase that had a great set of models in it. With that and what I already had, I'm planning out my 2000pt list now. For context, I play pretty much exclusively against my friends who do Marines, Deathguard and Necrons armies. It's also very difficult to get forgeworld models into my country at any kind of reasonable price, so I'm doing my best to get by without Dimacherons and its ilk. Aside from that, any and all advice/feedback about what I could do to improve the list is welcome.

I don't know what's the intent of the 3man warrior squad in kronos, since they don't benefit from it. 2 rippers should suffice for objective holding.
I feel that if you drop those, you could prob replace the broodlord with a walk tyrant with a cannon/spitters and rending claws for a little more use. But that's just me. I do like them tyrants

Alternatively, you mgiht want to trave the warriors and trygon for another exocrenes, then you can drop murderous size and give the physiology to the 2nd exo
