The Bloodlust trinket is not really good at all for ferals might look like it on papper but it is not really the ideal structure of a trinket. The deal would be different if it was another stat like Mastery or Crit probably.
You would want to wear Bad Juju and the Valor Trinket. Here you have a pretty acurate trinket list.
And as you can see if you have Elegon trinket of some sort upgraded or the Darkmoon Trinket upgraded they might be worth to keep.
