Got an almost complete Keeper of the Lake; healer left on the last boss. Whenever I am filling a spot I often ask "leave, kick, or dc" just to get an idea of what to expect. They say that the healer left. During the final boss it became very clear why. Tank kept spinning the dragons, hitting everyone with the breath attacks and at one point I had to rescue them towards the correct ad to tank. Got a clear so not really that big of a deal, just thought it was funny how quickly all my questions were answered.
