i recently started leveling black mage, i couldnt find any decent advice on when to use triplecast? im lvl 70 on it. i figured shouldnt use it when leylines is up because it would be redundant and wasting leylines. when should i use it? only for when i need movement? or perhaps between leyline charges? does it get any changes after lvl 70 i should be making a habit of?
