Basically showing the golems/core health etc, kills the idea of "sneak charging/sneaking" which is the most important thing in conquests, and without that, you can already see the number in the tab the only thing that can be discussed here is warping-time and a Scoreboard with just a warping time wouldn't make any sense IMO. Also seeing the number of kills wouldn't really help or make anything good from the player's perspective, just a cool thing if you are spectating the conquest or live conquest streams.
