Teams and shuffle

How teams are balanced with its own skill rating (NSELO2), team preference streaks and enemy groups.

Skill rating#

The servers keep their own skill rating, NSELO2, separate from the official Hive skill. After each round every player gets a chat message with their rating change, and the full details are on NS2Stats. Ratings feed the shuffle and the skill tier shown on the scoreboard; there are also Tier 8 and Tier 9 above the vanilla maximum, plus commander tier insignias.

How the shuffle works#

On the main server, teams are shuffled before a round when enough players are present (or when players vote for it). The shuffle:

  1. Builds several random team splits and improves each one, trying to respect what players want (their team preference and friend groups).
  2. Looks at how long each player has been denied their preferred team. Players who keep getting the team they did not want are favoured next time.
  3. Keeps players in the same enemy group apart.
  4. Among the best candidates, picks the split whose predicted win chance is closest to 50% using NSELO2.

So your door choice in the ready room still matters: it is your preference, and a long streak of being moved makes the shuffle more likely to honour it.

Enemy groups#

Don't want to be on the same team as someone? Add them to your enemy group: hover their name on the scoreboard and choose Add to enemy group, or type !enemyadd <name>. The shuffle tries to put you on opposite teams. Enemy groups only last while both of you are connected (and across a map change).

Friend groups#

Shine's friend groups (from the scoreboard) let players ask to be on the same team. Large friend groups are harder to balance and may be split.
