Hello, There is a feature that will be very popular in Honnorbuddy: Add a character in a "White List". When you're in bg, check your bot's whitelist. If a character is found it will heal for priority. This way you can Healbot your friends and other players who generate a large number of hk. (Sorry for my poor English)
then this should be in the CC of all classes that can heal, as of the CC decides what spells to use on what target, and 1HK =/= 1HP so id wouldn't make any sense tbh
