I can understand reducing the initial healing amount. In mission gear at 50, it heals for about half my health, that's a huge boost in any encounter. Removing the HoT doesn't make much sense though. Switching it out for a 15 second 15% hp increase? Great for tanks, but the rest of us get nothing out of it. But the kicker is the heal amount. It heals the same as the 48 Medpack. Am I the only one that doesn't see the logic in that? Instead of nerfing it to not be overpowered, you made it marginally more useful to tanks than the 48 medpack, not any more useful than the 48 medpack to everyone else, and cheapened its value by still having it require a BoP alloy to make.
Hurray "balance."
