If these daggers end up becoming GUI-focused I would be scared of the ramifications of Burn + Silence since those are 2 statuses that a VA perfectly plays around, with Burn's strength as it is I don't know about that, they'd quickly become "The Best Daggers" once again.
Maybe if you removed the statuses all together, one class' ability shouldn't be the sole counterplay to them, if you removed both of those statuses you could probably end up bringing these things back to a GUI focused scaling, but I am in general agreeance that STR scaling daggers are just bad, its not really possible to build STR GUI in the same stat-set without sacrificing too much simply.
