There was a time when I would have totally agreed on the 'no DRS' thoughts, but after getting used to the system and watching the Indian tests, it annoyed the crap out of me when there was no DRS.
Yes, it will have dramas, yes it will cause issues, but it takes out the dodgy calls and provides more strategy to the game. You also quickly figure out who the super selfish players on the team are... *cough Watson cough*
For those that don't like it - would you rather the anti-climax with the use of the DRS, or Australia losing the Ashes due to an absolute umpire howler sans DRS??
