Worse is the problem of Lv50 and 60 players not understanding the importance of a big (1) over a mob's head.
Using marks when they are mechanically unnecessary promotes bad play and decreases the impact of mechanically important marks.
Pre-30, the mobs that should be marked are
- Tam-Tara: During final fight, Imps if DDs don't understand that they're shielding Galvanth
- Copperbell Mines: During the slime fight, Ignore on the slime or bombs if necessary, (1) on the spriggan.
- Copperbell Mines: The last boss so DDs don't waste time on the mobs chipping away at the wall
- Toto-Rak: Graffias's Tail to stop it from turning the entire floor into a poison puddle
