point out little things that your team might have missed

like healers in CS having to spam heal to cope
giving a heads-up for patrolling enemies
giving advice to classes you know well (like placing Eos/Selene near the tank during standard tank/spank boss fights)
Generally just be good, polite and willing to learn from mistakes~ A tank who realises that the healer can't handle the entire last corridor in WP and pulls the first mob+tons instead of forcing us to wipe 4-5 times~ they will always get my comm regardless of stellar performance from any other~
