Encephalitic Diffusion stacks with Catalyst though, making whatever that unit is even more resilient. It makes the Maleceptor itself pretty hard to hurt. Alternatively it stacks nicely with the -1 to-hit from nearby Venomthropes and you can throw the 6+++ from Leviathan on top. It's moving Melta, Autocannon, and bolt weapons down a bracket on their primary targets. That's an interesting little stack of defensive buffs you can have going over potentially a lot of units. The flip-side is that yes it's a walking castle that can only spread out so far and it falls apart once the defensive pieces start dying. I'm not sure how well it would really work in practice.
I also think it's worth mentioning that Psychic Overload has potential to spike to 18 MWs and it's not an actual psychic power so it can't be denied.
From a list-building perspective I like that every slot outside Fast Attack and Flyer has at least one Synapse Creature. I think most 'nids with Synapse are paying a bit too much for the privilege but I like having the option.
For what the DG codex looked like and the leaks we're seeing for Dark Eldar, I'm wondering how much Tyranids are paying now for how good the 9th ed codex is going to be when it eventually drops.
