Currently my guild is still working on clearing ToT. We are a casual raiding guild, but we do have some really good players. We have struggled in ToT because some of our DPS is not performing up to their gear level. People with much lower iLevels are outperforming them and I'm not sure how to go about addressing them because it is making our progression very difficult. They are very nice people and have been with the guild for a long time. Should I try to work with them and make sure they are using the right rotations? Also how do I address them without them getting defensive about their performance? Any advice is greatly appreciated. Thanks.
