This here is something that internist me to know what would be the best group build (and to see if what class if any would be less used) this is for Raids and fractals (I know fractals does not really need this as much but just putting it up as an option as well)
The idea here is you have 10 players that are extremely good at there class so for example 10 Warrior (and its elites) 10 Rangers (and its elites) 10 Mesmer (and its elites) etc.
Now I know I put 10 in here and I know you would not want 10 of one class in a great preforming raid (and can't have that many in a fractal) but this is so you can mix an match with no need to have to replace a class with another because there not there (and I know could of probably left it at 5 each) .
So the idea how many of a of class. I know you got your dps, your healers, your tanks, your boon supports etc. I know some class like the ranger can do at least 3 of them good, and I know there are different raids that will call for different build
This is why I want to see (the players Ideas of the best list) so
WHAT CLASS WILL BE LEFT IN THE DUST
