we had to study what was happening
Bear in mind that the Manaan flashpoint is a tactical flashpoint for Swtor Credits, which means that it's designed to work with a suboptimal group. In theory, you can run a tactical flashpoint with the first three players who queued up. There are items like kolto stations in boss fights, so even if a group happens to lack a healer, it could survive the encounter. My group just happened to be a tank, healer, and two DPS; the healer and I were well over-geared. This made the majority of the fights super easy.
