Lots of Tank players are confused with Direct Hit, making it the meld of choice for endgame content instead of the intended Tank Stat Tenacity.
Currently right now, lots of Endgame Tank players who melded Direct Hit on their gear are using the Direct Hit melds as a tool to harrass non-conforming Tanks who use Tenacity instead.
Maybe SE, can help fix this issue by disabling Direct Hit stat if your job is a Tank and buffing the Tenacity stat instead so it will be the Go To Materia for Tanks.
