Im not usually a tanking druid but while soloing the raptor boss for the first time since the patch, it went much smoother. Usually I have to jump off the platform and heal several times. I was able to kill him without switching out of bear form at all today. Savage defense has made this encounter easier for me it seems. But the raptor boss does have a very slow attack speed, and Im guessing that against multiple mobs and fast attacks, the lost armor would probably fare better.
