I can remember Parsers/DPS meters back in EQ around Kunark. They have always been around and have been an amazing tool to help out a guild or group.
With the tools such as DPS / Heal meters it allows a guild to quickly find out holes in your current raid make up and fix them to complete content instead of going WELP lets try another healer? maybe 3 more DPS? maybe maybe.
You can examine this data and make a good call to save your guild much time and headache.
Anyone who has run a raid will always agree that a good Meter/Parser is a life saver when it comes to making decisions to better your guild.
I dunno why we even have this thread to be honest, you don't like a meter , don't use it. That is your choice but you will be missing out on alot of the fine details of how your class works.
