When I first started the game as Archer, I used to have the habit of locking target on random mobs outside of Gridania and spin around them and backing off at the same time to avoid getting hit too frequently. Leveling painfully slow that way before I understand the usefulness of FATE later on.
Then I picked up Conjurer for abit after knowing I can crossclass Cure for solo-ing before 30. I used to have a lot of problem selecting someone on the party list to cast Cure so when I got Medica I spammed that one instead because targetting allies and Cure was too hard for me. 8D

Those were the days, now I bard hard by playing the corresponding song and DPS standing still as well as can stance dance as healer after a significant APM improvement in the game.
