I always wated to use holograms but they just suck. You can always tell one. I suggest the following:
Programable hologram, here are some examples:
1- a hologram that dodges left to right from point A to point B
2-a hologram that has a programable path, think of it like setting some way points like in Starcraft where a unit comes out of it's base and follows a set of points (this would be great for a pred, he can sit back and create all sorts of diversions and have the hologram run around an AA like on Origin or Eco) Any mech can use this
3- Select the type of mech that is moving around (a scount can release a hologram that runs around but is a Incinerator or tech) Everyone chases a tech so this would be great
This would make the Hologram more fun and players would spend HC/real currency on it
Another thing you could do is have different levels of it, so the tier 3 one you can choose which mech you wanted as a hologram but tier 2 only moves around as the mech you play, tier 1 it just slides from left to right like you're dodging an attack.
In the middle of a fight this would confuse the hell out of me briefly.
