Pros: Can see the class (important) and battle rank more clearly. Cons: Placement of the box is too close to center of screen (at least on my system, I assume it's independent of resolution, FOV etc.). The glow obscures far too much of the field of view. Hard to see enemies, or what friendlies are doing. Any info box, regardless of size, can be a distraction. Suggestions Allow the info box to be turned off - it's not exactly critical information. Add faction, class, weapon and battle rank to the chat box notification - option to display as text at the bottom might be nice too. The faction is important if its friendly, as the id of any friendly accidentally tked is useful so a /tell can be sent, after all enemies have been cleared, with an apology. Allow controlling the size of the info box in Options.ini so players can chose a comfortable setting. Notes The xp appearing on the screen is used by players to determine when to stop firing - it should remain prompt.
i disagree with option of turning off, as like OP said, knowing when you just TK'd someone, can be important. i'd love this option: just like HUD has a "centralized" option, make the Kill window has a "Minimum" option, showing only faction icon, name, and maybe class, in a much MUCH smaller box, no fancy glow or anything, located at the bottom of your screen, and disappear much faster.
Cons: After noticing the animation time during play, and testing it in VR, it turns out the killbox animation takes quite a while to put the killbox in the center of the screen. Something like 0.5s, even longer? I can stop shooting quite a while before the kill info box appears. On weapons with small damage per mag, Vanu weapons in particular, this results in quite a lot of bullets wasted in situations where they are needed. Vanu Carbines/ARs only have 30*145 damage bullets (TR have 40, and the NC have 30*169 damage bullets). SMGs with low damage bullets, and the rest with 25/30 higher damage bullets are also affected severely. The full-auto infiltrator scout rifle only has 25*143 damage bullets IIRC. CQC situations are where all the important contests over points/gens/terminals occur. They too often throw more than one enemy, often unexpectedly, so saving bullets is important. Suggestion: Remove all delay so the kill info box appears instantly, or give us an option to do so. Does the client check with the server before the kill box appears? If so, since hit detection is client side, a mechanism to know when enough bullets have hit the target will help.
