Hi,

I have change from DBM to BW and i really like it :) but the only thing is BW have no taunt warning in raid, could you please advice me ?

Thanks in advance

We do not tell players when to taunt.
We inform you about tank abilities when they are cast and any debuffs/stacks that are then applied.
We try to make it more obvious that stacks are high. It's up to you to decide when you want to swap.
If you feel some tank warnings are missing, you are free to request those.
