I have been thinking of a build for raids, that could be a healer and a tank at the same time. Came up with this: http://gw2skills.net/editor/?vFAQFAWn0XC9XitMAWYCcYilNAb4BEAugu71/6hlYFkCqAA-TxxGABLp8bo9HA4CAshOAVU/h8HAAeKBDAgAwP/5P/5P/ZpA8bqF-e. Would this work in a raid scenario? Note, that this is definitely not a perfect build, just wondering if it would work. It would take the role of a healer and tank at once.
