Grid2HealsIncomingImproved

This addon adds a new status to Grid2 called "heals-incoming-improved". It provides better heal estimates than the built in "heals-incoming" status. It also counts the number of healers on a unit and predicts when you will overheal. 

See image in gallery for how to swap in the new status for your heal predictions.

This addon is for classic only. TBC, wrath, and any later expansions are not supported. 

If used on a "bar" indicator in Grid2, this is a drop in replacement for the "heals-incoming" status. "heals-incoming" forces you to either use LibHealComm or the default blizzard incoming heals API. If you have  LibHealComm and all the other healers you play with also have it, then this addon will be the same as "heals-incoming" using LibHealComm to predict all heals. But unlike the "heals-incoming" status, this addon has a fallback when you or the other healer don't have LibHealComm installed. It will caclulate incoming healing by estimating the other healers healing power from their previous landed heals. After a few heals, this addon will be able to estimate their future heals pretty well.

If used on a "text" indicator in Grid2, this works similar to Incoming Heal Checker weakaura. It counts the number of healers currently healing the target. 

If used on a "color" indicator in Grid2, this also works similar to the above weakaura helping to predict overheal. The color is white on units others are healing but you're not, green on units you will heal, and red on units you will overheal. Because this addon has a more complicated/accurate incoming heal calculation it can better predict when you will actually overheal. Currently the overheal warning triggers if your heal will be more than 70% wasted.
