Why is the sentinel the guard cast?

[Szunti]

Sentinel looks bad at guarding to me. If she camps doors and tackle spams, that works, but you don't have to be a sentinel to do that. But if a host gets out of the nest I don't see any way to put them back with a sentinel. If you miss a spit, or tackle fails, they are running even further from the nest. Drones can capture hosts again if they are downed by building a new nest and they can camp doors just as well. The only thing that sentinel can do better is cornerspitting into the host's cell. Are sentinels born to cornerspit checkerboard nests?

But perhaps I just play it totally wrong.

Neurotoxin can be fired rapidly as a sentinel you really cant miss....

Sentinel can shot neurotoxin diagonally, so the marines dont even have the minimal chance of escape.

there's many reasons why the sentinel is the guard caste.here are the main examples
1)they can use the things the drones build to their advantage more.it can use them as cover,use the sticky resin to hit marines easier because they aren't moving so fast.
2)they move a lot slower than the hunter caste.This makes them worse than runners at collecting hosts.
3)they can melt things making new room for the hive or eliminating threats like guns,grenades etc.
those are just 3 reasons I can think of as to why the sentinel caste is the guarding one.

This. and many other reasons stated before.

Its more sensible honestly since they were intended for guarding anyway.
And if your the kind of fuck who plays Combat Sentinels i will find you.

Yes. Sentinels are designed to guard, and if you are gud they do it well.

the thing with sentiels is they can drag u immediatly after they stun u unlike hunter/runners who are stunned after pouncing and drones are way to slow and dont have a ranged stun

[Szunti]

The only safe way I know is to stand next to them and tackle them as soon as they get up before they can escape / harm themselves. Like this:

o=door, H=nested host, X=sentinel
  o
 oHo
 oXo
 oHo
  o

But it doesn't need neurotoxin at all. Every cast can do it. Sentinel doesn't really have any advantage.
Of course you probably have to guard more or they are more separated. They will synchronize their getup and try to escape/kill themselves. You can put back one, but the other primes a grenade, destroyed the nest, put his gun into his mouth etc. If the host is bashing his head with a crowbar, or shooting himself, then you can spit them quickly whitout opening the door, that's something. Destroyed nest can be handled most easily by a drone imo. Build a new nest outside the door and drag out the host. The point is neurotoxin is an advantage in some situations, but in others the speed of the runner or being able to build can be more useful.
On the other hand a shotgun loaded with buckshots doesn't look that scary as a sentinel. Lone hosts are mostly easy prey. So a sentinel is really not useless in combat. And as I see they are designed to hold narrow corridors, get lone hosts without harming them, support hunters with their longer range stun. Not to watch nests.

Their cornerspitting ability is suited to it but neuro is harder to use in combat with a limited range. The fact is they're not strong enough to do other stuff as well as other castes, so they're resigned to their role as babysitters.
