Blessing of the Bronze has been an interesting “raid buff”, but it’s honestly a meme at this point of the game where you class/spec is brought to content for its raid utility and group buffs. I’d like to see it reworked in the future. This is speaking from a mainly Pres point of view since we can’t use our other “raid buff” SoM in 5 man content or on ourselves.
Some ideas for a new BotB that keep with the bronze/time theme could be a flat 3-5% haste buff since it’s one of the few stat buffs that isn’t taken yet. That’s the easiest fix.
The more interesting choice could be your spells cooldown 5% faster. Is this just a nerfed version of interwoven threads from Aug? Yes. I think it fits thematically and could be cool to differentiate from the usual “here’s your raid buff stat stick” style we see right now.
Do I think that every class needs a raid buff? I do not and I don’t think it’s healthy for the game and for the “meta”. Do I think blizzard has any plans to prune raid buffs? No. So why not give the least represented class something to at least make them desirable when joining a group/raid.
