Cross-realms dungeons are awesome, players sometimes aren't wow gold. Rankwatch is one of the most useful mod I used, it will monitor the spells cast by you and your party/raid members and warn them if they are using a downranked spell. A lot of people are running around and use lower ranks of spells because they never changed their bars or trained them after dual speccing wow gold, or even just because they use an outdated/bugged bar management addon.

It's also very useful when leveling an alt, when the amount of lower ranks becomes too high you know it's time to train! Of course it's nothing compared to the joy of knowing you made the world of cross-realms dungeons better because the addon yelled at your paladin tank when he used his Rank 1 Consecration in the Halls of Reflection wow gold.
