My first Instance was deadmines. Running my team had been sweet until here Macros running well (or so i thought) content droping like flys then I hit DM and it all changed. I think once you hit an Instance it can really change your setup. My healing macros were a complete failure as they had been untested until then and my DPS rotation was terrible and my adds were placed poorly and adds were a problem. With a little tweaking everything went smooth on run two and have ever since with the exception of the lizard guy in ZF and Princes in Mauradon (but I will spank her today... fingers crossed). In my opinion, outside of instances teams pretty much rule its inside where you really test your setup and must overcome boxings weaknesses and releavl in its strengths.
