See everyone defines "useful" as something different, having the best gear and no clue how to play the job, joining every shout is
NOT useful. Playing drg cause the shout NEEDED a drg, and you HAPPEN to have it 99, with a ryuno 119 DOES NOT make you useful.
Being that drg, with the intelligence to use meds. Use Ja's. Use food. Use PDT, have actual proper gear, not just agnon hands, makes you
USEFUL.
Being a mnk with brotixur does
NOT make you useful. Having 99 brd does
NOT make you useful.
Understand what I'm saying?
