Hey Finley,
You dont need just vets, chimeras and vendettas. Other units are capable of fulfilling objective missions, in just a different way.
For example, scouting walkers, can pop up and negate enemy objectives, even if they cant capture. If you use Alrahiem, you can scout an entire platoon.
Regular guardsmen can use chimera if you dont want to use vets. I often give chimera to my regular units.
Storm troopers can deep strike, they can invade enemy objectives.
Remember, you can interfere with them scoring their own objective with non troop units, you just need to ensure you actually have troops on your own.
Dark eldar are evil. The player in our group has virtually his entire army mounted in raiders. If you don't manage to kill most of them before they get you in hand to hand its game over with guard. He can easily aquire feel no pain too, negating a lot of their supposed weakness of being low toughness and armour.
I would avoid all competitive 40k sites for list building advice, although they can give you a reasonable idea of what is strong in a list. You tend to see what I call photoshop lists [eg the same thing repeated over and over in all slots]
Aldaris: Obliterators are great. But I agree with you, the internet will have you beleive it is literally impossible to win without them. I often play with just one, or maybe two in total. No where near the recommended 3x2 in my heavy slots.
