The situation with feats and especially soulblaze needs tuning, but I would rather we get a quick fix for BB before any other changes because it’s such a core feature upon which other feats depend on.
I already suggested a minimum of 2 changes after which we can see what other changes or re-balances are needed.
Formatted version:
BB damage that scales with BB charge time which scales with target HP, is also an interesting idea and would help BB remain viable in higher diff tiers.
