Granted, I think they were a bit nerfed here because they omitted the aerial support. No spaceships or any other tech machines present, and I feel that was done in part bc they wanted to have Thor/GotG save the day as the team on the ground got overwhelmed.
Now maybe the ships wouldnt have fit inside the dome, and didn't want them flying outside the dome, or any other theories we can make for it, but their omission was noticeable to me. I dont think ppl would've got mad if they showed some Wakandan toys doing damage, bc the shield itself was cool and half the general audience prob thought this would be partly BP 1.5 anyway
I think its more so Wakanda would've wrecked those aliens, and then they'd have to further up the ante/fukkery to make the Thor moment still be necessary
