Yes, all combat addons are gone. You don’t need one now.
- turn your party to frames
- move both party and raid frames to where your addon is
- Turn on mouse over casting so you can cast on frames
- Turn on “Show Debuffs” and “Show only dispellable debuffs”
- Heal
pro tip, get a gaming mouse like a Naga or at least one with 12 buttons on the side. I run one and have never needed a healing addon since they added Mouseover casting to the base game.
