Using reflection probes in outdoor scenes

Hi everybody. I don't have much experience working with reflection probe and I really think that the way I am approaching my scene must be wrong. I have this arena map for a multiplayer game and I am basically adding reflection probes to cover the whole map,indoors and outdoors. It feels extremely awkward to place and re-size the boxes to fit the map areas. The player has metallic weapons and I would like to achieve good-looking reflections, that is why I am covering the whole map.

I have watched some tutorials of people using several reflection probes to cover corridors and stuff like that but I haven't found anything that helps me address my problem. What is the proper use of reflection probes in these cases?

I am aware of all the cubemaps generated by the reflections probes, I do not know if it would be better (performance-wise) to parent a real time reflection probe to the player (I have no clue if this is possible or if it would work properly)
