When you're only in there to gain access to a couple pieces of lab equipment it feels a little tedious having to hack away at 20000+ health doors for five minutes. I get that these are supposed to be hyper-secure ancient vaults from the "before-times", but when you have to hack through 1. The outer Vault Door, 2. The inner vault door, 3. Each of the smaller vault doors leading to the different areas, 4. the actual beacon that leads to the next vault, and 5. any assorted storage crates that might be scattered around.

All together, considering most of the vaults I've found have had one guy guarding them and maybe a single functioning turret, makes tackling these things just feel like you spend most of your time waiting for things to happen. It just feels excessive when there's only really a few things I actually need to get from inside, and breaking down the door takes about the same length of time so that's not really any better.
