For those who do not know, Rally used to apply a Heal over Time as well as having the ramping burst heal at the end. Though it was sad to see it go, it wasn't really all that game breaking at the time. With how PvP is right now, even when you manage to avoid someone's burst the Damage over Time effects they have put on you will whittle you down.
How do we deal with those dots? Well people turn to sets like Mara's Balm. In the past, dots were still needed in PvP to an extent but now they feel far more powerful than before especially when light attacks are hitting for 2k damage even with Battle Spirit (Maybe battle spirit should reduce the damage of light attack by some amount?). Having that tiny little heal over time that will bring your heal up by around 500 every second can really help relieve pressure.
Mutagen was the other morph of Rapid Regen, it lasted 20 seconds and when you reached a threshold of health the healing effect would be consumed to give you a small heal right there and then. In addition that that consumed heal, it would purge one negative effect. This ability would serve a similar purpose to Rally's Heal over Time in that the heal over time will help relieve pressure but it also gives people a way to cleanse things without having to turn to a set which everyone and their mother decides to run.
