I know Adventurer in Need doesn't count, but it ... is probably still used as a metric to see if we still have more healers ... Before you get the pitchforks out, I have actually tested it out too. Since I was seeing way too long periods of tank being needed for hours and started to suspect something wrong. It was as you said half the time, Supersnow, with a 5 - 8 ish minute wait as a tank who is supposedly "needed". Switch to healer right after that and I got in instantly with no AIN bonus >.>

So... those mounts that were needed as tank queuing achievements ... It looks like the healer versions are needed too now >.>
