They take a while to light up in order to limit the RNG factor involved in them.

If there wasn't this delay then fights could be decided without any input from ether Fiora or her target. Fight goes on, mark randomly spawns on the side Fiora already is attacking, chunk of damage which can't be reacted to by ether party.

With the delay, if a fight happens and a mark spawns towards Fiora, then both she and her target both have time to navigate around each other. It's still RNG, only now it gives you and the other champion the information to react to it and adapt.
