The DS is implied to be extremely old, likely from the times where people still wrote on rocks and walls using stick figures and such. That could easily be hundreds, thousands or even millions of years. If in all that time a Grimm didn't become much more inteligent than a "newborn" Grimm, then their only real strength (that they get smarter as time passes by) becomes an Informed Ability and they become even more of a total joke.

Phantom said somewhere that maybe it was old, but lacked experience, which is a more reasonable explanation. And if it isn't the case, then Monty, Miles and Kerry fucked it up. Alternatively, given the time period implied by a cave painting, it could just be that the Deathsalker had never encountered powerful Dust-wielding humans and did what it thought was all it needed. Before it could grasp how different their abilities were from the humans it encountered in the past, it got killed. When you consider how the Deathstalker and Nevermore worked together, they clearly showed intelligence in combat.
