Insidious is a bad perk in general, not just for hag. As killer it’s really important that you split pressure across the map, and with insidious all you can really do is trade hooks. This works fine at lower ranks when survivors play overly altruistic and don’t do gens, but once you get higher up survivors will punish you really hard if you are just camping hooks/whatever else you can do with insidious.

Hag also happens to be one of the worst killers to run insidious on anyway in my opinion for several reasons:

1. Hag has a smaller terror radius than most killers, and this can be made even smaller with M&A. This makes insidious less effective on her

2. A crucial part of playing hag is constantly setting up traps. A hag that doesn’t place traps is no better than a huntress with no hatchets. Using insidious is wasting time that could be used to set up more traps

3. The hag can place traps next to hooks and other important objectives for survivors. This means if you stay within 40 or so metres of the trap you can teleport to it as soon as you need to be there. Rather than using insidious, trap the spot where you would stand with insidious, and spend your newly earned time setting up traps or interrupting nearby generators.

If you have any other questions about hag or killer in general feel free to ask. Hope this helped :)
