You can see your level of hate by looking to the left of your party frames. There's an Enemy Target Frame and it shows whether you're okay (Green), getting a bit too much Hate (Yellow), really need to watch yourself or have the tank swap to that add (Orange), or need to hit Shroud RIGHT NOW PLS CUZ YOU'RE TANKIN', BRO (Red).

You don't ever need to swap targets to watch your threat level.
