The Burning Crusade Beta is currently missing +healing combat text above players heads. When you heal a friendly player or unit there is no +healing number above their model.
Here is a youtube video from May 2008 where this can be seen, check the green +healing numbers above the arena partner at the timestamp: https://youtu.be/dc0WrORiHmM?t=99
Additionally, here are the interface options from the original 2.4.3 client, showing the toggle for healing combat text: https://i.imgur.com/XQb5J5o.png
Is this a known issue and are there any plans to fix it?
(I reported this bug on the beta very early but there is still no fix in sight)
EDIT: In fact it seems as if they copied the floatingcombattextcombat cvars from classic and forgot to add the following:
floatingCombatTextCombatHealing
(Display amount of healing you did to the target)
In original TBC 2.4.3, the cvar was named as CombatHealing
, the above is the modern retail version accomplishing the same goal.
