Background: I have 270+ GM clears, gilded conqueror x4, 200+ raid clears. More than 70% of the GM clears were done with a solar titan utilizing Hallow fire heart. My strategy was always to pull aggro away from teammates and use my reliable abilities mainly thermire grenade to regain my health by pulling the attention of the fight towards me. After clearing the adds I would try to use a sunspot to regain my grenade and and deal some improved DPS. My priorities would rank as follows: [b]Attract attention without dying > regaining health > bonus damage.[/b] So I don't mind loosing the bonus damage but we also lost both of the higher priorities in a much worse sense. It would be impossible for me to gain health while attracting aggro and over exposing myself by going out to the open to stand in a sunspot to regain heath. So when I attempt to attract more challenging combatants (GM level) I wouldn't be able to survive even with a perfect setup and execution. Additionally running hallowfire heart requires a full sacrifice of your super and the number of fragments which effects your super is far greater than the number of fragments in the void setup which takes more for running hallowfire heart than previously and nothing is gained for this. Roaring flames is not ideal for most challenging content especially in the way Bungie indicated we should use the perk (see patch notes 24th May 2022) I would sacrifice this aspect for more control of my health regen. I'm deeply saddened today, I understand that Bungie does not want power creep to exist over run the game but bottom tree solar was already in the low usage/pick rates and I don't see myself enjoying the new system.
