What makes a good tank in a MOBA? A tank's job is to attract attention and attacks, commonly referred to as "drawing aggro", while making sure they are alive long enough for the rest of their team to be able to achieve their class' goals. Many people consider Tanks to be a leader of sorts since they are the ones to truly set the pace of an encounter. They sacrifice damage in exchange for a high health pool, and even those without a high health pool can get by with the help of a support unit.
