Hello,
I have been playing this game for 10 years and have always been a healer. Both priest and druid. The last years I've only played druid.
The way healing currently works with either priest or druid is in dire need of a rework.Healers don't have mandatory stats that they have to use. The only thing that counts is the items used and how high they are tiered. Also, especially with druids, the HoTs with their caps are very low and almost useless with the current gear. This will not change in the future if healing in general and the HoT caps aren't reworked. A tank with 3 million health gets a HoT with 36.020 from recover, very low compared to nowadays hp values and with little impact. Healing at the moment is mainly reduced to either mother earth's fountain and recover on a druid or urgent heal on a priest. Healers basically can stat like tanks without any wisdom and still dont loose any healing due to the low wisdom cap. What are the wisdom stats for? There should be must-have stats for healers to that directly impact your healing output.
E.g. it would be an approach if you do something in the direction that the healing on the items scales with the wisdom. For example, if you consider 100k wisdom as 100% healing, an item with 5k healing at a wisdom of 50k will only give 2,5k healing effectively, so 50% less. If you had 150k wisdom, the item would give 7,5k healing.
This would at least in some way force you as a healer to use certain stats.
