[TBC Outlad] Raid trash spawn timers

I may be wrong but i feel the trash spawn timers are way off. If i remember right they were on 2 hours timers in retail. Seems like they are around 30 min. Is 30 mins correct or not, and if not is this something that is suppose to be fixed in the near future? Thanks

There are spawn timers set to 45 min as prenerf timers. On retail that was changed to 2 hours with Black Temple release.
