In TBC, hardly any bosses in any of the dungeons have timers or bars is this as expected? I am unsure if there is some bug or there are only a few timers.

What steps will reproduce the problem?

This can be reproduced by playing any TBC dungeon

What version of LittleWigs are you using? (Stating 'latest' is not useful)

v7 classic bcc

Do you have an error log of what happened?

No, there is no error log produced

Any additional information? (example: WoW language if not English)

It's unlikely this will change now that BCC is ending.
