Remove Cooldowns from Three Perks
So, the perks that have to do with hooking and downing survivors should not have cooldowns, because that is not something 'chosen' to do at any given moment, so much as the end goal. It makes no sense to not be able to use your perk because you hook or down a survivor too fast.
That is why I am suggesting that the cooldowns be removed from Surge and Hex: Blood Favour. I am also pretty sure (But not certain) that Blood Echo has a similar situation where hooking before the cooldown does not re-exhaust injured survivors; it should. It's not like you can hook a survivor on demand, like almost any other perk with a cooldown.
Second, but only similarly related; Dark Devotion should refresh if you hit the Obsession a second time before it is over.
All other Cooldown perks besides these four activate when the killer/survivor chooses to perform an action, or when the action is immediately related to the benefits (Visionary/Zanshin Tactics/Windows of Opportunity). They stick out as outliers of "doing too well is not rewarded because CD".
Edit: Additionally, I do not think these perks are so powerful that this will swing a massive unbalancing of them. Each perk could probably get this increase and still not be meta, but still be more useful.

Hex's shouldn't have cooldowns to begin with aince they can be taken out of the game easily
A good point. Blood Favour is the only one.
