No functionality has or will be changed. This is purely a hotfix so it can continue to work in Classic Era.
This addon was designed for Blizzard's UI only. However, you may find that it still works with a limited number of Unit/Raid Frame addons.
HealBarsClassic brings healing predictions to Blizzard's Classic UI. There's no need for complicated setup, simply install and adjust one or two options to fit your own tastes. You'll have all the info you need to be an effective healer, including when someone is protected by shields or a major cooldown like Blessing of Protection or Shield Wall. That way you'll always know where to prioritize heals.
The newest 3.0.0 version brings an option to have separate colors for your own heals. While this option is enabled, heals are shown in the order in which they'll land! You'll no longer have to worry about overhealing just because somebody is casting a faster heal on your target. Enable it from the settings with /hbc
This addon was formerly known as HealCommClassic and was renamed to avoid confusion with LibHealComm (commonly just called HealComm).
Incoming heal bars
Separate HoT bars
Separate colors for own/friendly heals
Healing communication with other addons (VuhDo, Luna, HealBot, etc)
Custom status text info
Cross-addon compatible raid check (See /hbc help)
HealBarsClassic has been designed for Blizzard's unit/raid frames only and compatibility with other addons is not guaranteed. These addons (and possibly more) are known to have some soft compatibility: Easy Frames
Blizzard's raid frames can become misaligned when players or pets join/leave raid during combat - This issue is a bug with Blizzard's raid frames and is not related to HealBarsClassic.
A game update appears to have caused predictions to update slower than the player's health. A fix is possible, but I (SideFlanker) don't intend to re-subscribe to WoW. Sorry!
