>Its very damning to the Theory of Evolution as said theory places a heavy emphasis large spans of time happening for any meaningful evolutionary change to take place

No, it does not.

Each new generation is a reshuffling of a species' genome. Each new generation is minutely different from the last. If we look at the gradient here:

Which pixel could you say is the start of red becoming blue? It's difficult to determine this. Yet if we take a close look at the gradient's pixels, we can see that each pixel is just ever-so-slightly different than the pixel before it. This is a visual representation of Evolution: "One Generation at a Time". Yet even with this gradient, this is what Evolution would look like when it is consistently going in one direction, consistently shooting for a particular trait. But we know this does not occur: Evolution's shuffling of the species' genome is randomized. Why, then, do we eventually get Speciation to occur? Because each successful generation yields a gene frequency slightly different than the last--we are 'stacking the deck' with more and more chances of something else.

>Creationist rely on these processes happening over shot periods of time.

Creationists do not rely on any scientific process. Creationists rely on Faith-like adaptations of events and phenomenon. Anything empirically studied derived from nature belongs to Science.
