I suppose if you're queuing as PLD, you have both Cover AND Testudo to help deal with ranged physical dps. As a solo-queuing healer, I can get WARs who don't bail me out with Thrill or DRKs who don't have any party mitigation buffs at all. Carnal Chill can only hit one person and Delirium takes 3 GCDs to get up. Also, if you've never healed in Feast before, just know that trying to keep someone up through Wildfire+Between the Eyes SUUUUUUUUUUUUUUUUUUUUUUCKS.
