Possible adjustments to ranked points
The current point system is pretty fair overall, but I think it could still be tweaked a bit. My suggestion is to make the kill/assist points worth half of their current value, add a feature that gives you an assist if you dealt more than half of the damage to a player before their death*, and give points for damage up to 1000 damage dealt. The damage points would mirror the kill/assist points with every 200 damage being worth 1 kill/assist's points. That way you can still get the same point totals as you do currently, and unless you're stealing kills or getting your kills stolen often, your points won't change from what you currently get. This makes it a bit better for situations where you deal 190 damage to somebody and they escape for just long enough that the assist timer runs out, and when your teammate hits them with that final bullet you get nothing for it.
*To elaborate on the assist changes: if a player heals after you've dealt damage, the amount that they healed is subtracted from your total towards the damage assist. For example, if you deal 140 damage and they use one syringe, the damage assist will only think you've done 115 damage, but you would still get the assist if they die before healing further. If they use two syringes, it would only count you for 90, so you would not longer get the assist if they have level 3+ shields.
I'd really like to see these features added, because ranked is rather frustrating when you are playing pretty well but not actually hitting the final shots and also not getting assists.
Edit to add a graphic, in case anyone is confused or if I did not explain well!!
