You can disable capture points in Custom Conquest to make custom layouts
As the title says, one thing that was quietly added in the Season 2 patch is the portal game mode "custom conquest" which gives access to the rules editor.
With this and a few new blocks in the rules editor you can disable capture points to set up new map layouts in conquest!
You can only do this with 6 maps so far and they are the 64 player versions, but its really awesome.
I tried setting it up with bots to see how the bots would respond and how the tickets work; bots react accordingly, but there doesn't seem to be a "reinforcement multiplier" or "reinforcements removed per kill" so you probably need to set something up in the rules editor if you want to adjust the number of tickets.
Anyway have a play at setting up your own map layouts!
Hopefully they will add the 128 player versions soon - this would allow us to set up way more layouts
