I usually have no problems with MP except on Garuda, but I usually steal the limit break and that effectively solves that problem and gives me some lee way. I keep everyone buffed with stoneskin after every pull and ESPECIALLY before a boss fight. DPS should be smart enough to avoid all avoidable dmg, same with tank. But if there is a situation where I know it's about to get hairy, I usually keep a regen/cure1 on the tank, and cure 1 on most dps when they get low. BUT if there is a situation where they have to chase adds, I usually just toss em a regen and move back to the tank.
