Sabotaging is a really cool concept, however it has been nerfed to the ground. If Saboteur were more viable, people might spend some time doing something other than Gen rush.
As it is now, Hooks stay sabotaged for only 2 minutes by default; in the past it used to be 3 minutes. Moreover, it is really difficult to guess which Hook the Killer is taking the Survivor to, and even if you guess right, they are nearly as fast as you are while carrying so it would not matter as they will make it to the next closest Hook before you do.
What about this buff:
Unlocks the ability to sabotage without a Toolbox at 50% the normal Sabotage speed. Hooks and Bear Traps you sabotage stay broken for an extra 30/60/120 seconds. The Auras of Hooks are revealed to you within a range of 16/24/32 metres.
At the moment there is no point in using the Perk if you have a Toolbox whereas the latter is faster. In order to solve this and prevent the Perk from becoming too powerful, the old Toolbox consumption rate penalty when used for sabotage should be brought back.
