I’m sure this is gonna sound really obvious and boring to veterans, but I’m impressed just how much information you can gather from the game just from the visual effects and nothing else.
You can tell the age, size, stability and class of a wormhole just by looking at it, whether a ship is being neuted or NOSed, whether someone has shield hardeners or boosters on, or whether he is repping armour or hull (or being repped). You can even tell what kind of ammunition and what subclass of it is being fired, and loads and loads more.
For all the s*** EVE gets, this is pretty impressive.
