Niagara arrows performed better vs animated ISM using a for loop with a lerp.
However the ISM performed better than niagara if not using any animation.
ISM might still be a good option in case meshes are only sporadically moved during the game or moved using C++.
So in the case you are using forms or units that rarely move, or move only when activated and are static most of the time, the HISM might be a better option.
In all other cases niagara is a better option.
