GetQuad! Nations Cup

Rules

League format: group stage (BO3) and playoffs with top 4 (BO5).
Maps are TB3, but if teams agree to play others, it is allowed.
Preferably teams are by nation, but if there’s not enough players from one nation, teams can be a mix of nations, but admins have to approve.
Players can choose to play within the team of their country of origin, or to play in the team of their country of residence.
Each team has to elect a team manager, who’ll have to deal with admins, schedule matches, and define team lineups for each match. The team manager needs to sign up the team for the tournament. Signup form
Server selections are up to the team managers, but equal pings are mandatory!.

TeamOverlay: the team, who is not selecting the map, decides the TeamOverlay setting for that map. For 3rd maps the TeamOverlay setting must be randomized (/rnd TO_on TO_off). But teams can agree on the TeamOverlay setting (always on, always off).
Timelimit: 20 minutes
Overtime: 5 minutes if match is a draw
Deathmatch mode: 1
Teamplay mode: 2

Players should do f_ruleset checks before game start. It is ultimately the responsibility of the players to perform this check, and in general, matches played with outlying rulesets will not be overturned, if the players neglected to perform this duty. Where there is ambiguity, the decision will be decided by the Admins.

Using disallowed clients/proxies might lead to points deduction or even a WO.
