I agree with a lot of what he says and maybe in the east coast meta he is spot on. For me I think he dismisses some considerations like hormagants and warriors.
Warriors since the 5ed dex have been decent deck chairs, you just didn't really need a deck chair with tervigons. Now that termagants fall back 50% of the time when they fail IB, I can see warriors being a default cheap scoring unit for bugs.
Hormagaunts gained an extra 3" run and base are more effective point for point then they were. This is where swarmlord comes in, giving them the USR they need to get the job done.
Look I am not trying to white knight the codex and I am 100% in agreement with his assesments on the core rules in the book. I just see some new units emerging as worth considering and that's a good thing to me.
