Pillar PvP V4.0

Welcome to Pillar PvP!
This is a map I've been working on and off for about a year now. This is the third version of the map I've uploaded, I deleted the other versions of this post so you will not find them.

If you find something wrong with the map please tell me, I am trying to make the map as best I can.
I am missing a certain feature for the map that I can't seem to add. If anyone can add scoreboard that would be great. I need a score board that adds a player when they join a team and removes them when they die. I need it to count kills and when they die, should reset the amount of kills they have. If even possible, it would be much appreciated if their names changed colors and PvP respected teams, and even if you could not harm another played until you have joined a team.

Thanks for looking at my map!
Enjoy! :D

Note: On teleportation to team spawns, if your computer loads chucks slow you have a chance to glitch and get stuck in the floor, I came across this and was unable to fix it.
