1. Do not heal me over my maximum HP when I'm on Warrior and Thrill of Battle is about to expire. I know it's hard to resist the urge to top the tank off but it's overhealing, wasting your time and MP.
2. If you know a big hit is coming and trust your Warrior tank enough to know he'll use Holmgang, let him take the hit to the face, reducing his HP to 1 then Benediction/Lustrate him back up. I just wish Holmgang stores all the healing you receive during the duration and heals you that after it ends but....
3. You can stand close to the Paladin tank if you're getting hit with physical attacks. Good Paladins will use Cover on you to take the damage.
4. If you see Hallowed Ground going off, it does not mean you don't need to heal me anymore. It just mean you have 10 seconds to get me and the party into a better state.
