Thank you, I find this post refreshing and actually doesn't aim to just blame tanks or dps for healer issues, I think it's important that yes some skills are overtuned on tanks, bloodwhetting for example you can never balance that skill to be fair in a AOE situation. In general it's a issue with How little tanks take.
I also believe bosses could even make use of skills like intervention, TBN ect. Where a ally healer or dps will take high damage, Either the tank or healer can be enough to save them, instances of high AOE damage and DOT debuffs with raid wides ect, Let pulls hurt even more, let me do even more big pulls as a tank (like mt.gulg that dungeon had some pretty thrilling pulls)
Let us actually Use our kits as tanks and healers. This is the more productive path of actually making both roles feel good in dungeons, raids ect, also have this reflect on hard content where healers and tanks are both needed.
