Most *players* don't know how to play their classes/jobs right. Its just really easy to see bad DRG since they apply buffs with three key moves.

I've seen tons of BLM who Fire 3 spam, or Transpose everytime they need to change cycles even after getting Bliz3

MNK who only stand in one spot

BRD who never DoT or sing or Silence

SMN who Ruin spam or let pets run wild

Tanks who only 1-2-3 and never AoE

Healers who spam AoE or Regen, or constantly overheal
