You summed up my thoughts perfectly.

You are forced to abuse the "meta" if you want to climb. So... You're forced to pick WAR/SAM/WHM.

I'm tired to see the same comp at every match with just a few variations like

WAR/WHM/SAM/RDM/SUM
WAR/WHM/SAM/NIN/(random player completely lost)

I had fun when I was Bronze and could clim playing Bard but this is over now
