This is probably a hard one, dont know if Carbonite can this:

The szenario ist timed to 15 minutes for the bonus task (you can get additional time for the main task). It would be nice to see the live timer in Carbonite aswell. Otherwise I have to use default quest tracker for this szenario.

Does any one knows other scenario with timer?

I dont know of any scenario, but M+ (aka Challenge) Dungeons have a similar mechanic?

Done.

@mikepauer next time assign yourself to issue u are working on :) i will do this in future too.

There was no working on :P I saw the request when I woke up and finished it about 1.5 minutes later
