Must have triggers...

[perhaps]

///Leaver///

   Events
       -Player - Player 1 (Red) leaves the game
       -Player - Player 2 (Blue) leaves the game
       -Player - Player 3 (Teal) leaves the game
       -Player - Player 4 (Purple) leaves the game
       -Player - Player 5 (Yellow) leaves the game
       -Player - Player 6 (Orange) leaves the game
       -Player - Player 7 (Green) leaves the game
       -Player - Player 8 (Pink) leaves the game
       -Player - Player 9 (Gray) leaves the game
       -Player - Player 10 (Light Blue) leaves the game
       -Player - Player 11 (Dark Green) leaves the game
       -Player - Player 12 (Brown) leaves the game

   Conditions

   Actions
      -Game - Display to (All players) the text: ((Name of (Triggering player)) +  has left the game.)This will of course inform people when someone leaves. It's annoying going five minutes into a game before you finally realize someone has left.

///Set Game Speed///

   Events
       -Map initialization

   Conditions

   Actions
       -Game - Set game speed to Fastest
       -Game - Lock the game speed
Needless to say it doesn't have to be fastest, but this is to force the game speed as you intend it to be played in.

Ah, that second one is helpful, didn't know there was such a trigger. i'll add that.

It does display a message when someone leaves, however. I'll be adding a sound to accompany that in .93

[perhaps]

    I wasn't making suggestions specifically towards your map with this, it's intent being simply a thread of "must-have" triggers for maps in general. But it's nice that you can make use of one.

World Edit can be surprising like that, "it has that?"

[Burning Rose]

Oh, okay then

[perhaps]

Well, I'd say this is a matter of preference... But I'd also say if you want for better replay value on battle.net. I suggest this...

JASSfunction EndTheGame takes nothing returns nothing
    call CustomVictoryBJ( GetEnumPlayer(), false, false )
endfunction

function Victory takes player p returns nothing
    call DisplayTextToForce( GetPlayersAll(), "Player "+I2S(GetConvertedPlayerId(p))+" has won!" )
    call PolledWait(3.00)
    call ForForce( GetPlayersAll(), function EndTheGame )
endfunction

And an example use for this...function ForTheWin takes nothing returns nothing
   call Victory(GetTriggerPlayer())
endfunction

//===========================================================================
function InitTrig_ForTheWin takes nothing returns nothing
    set gg_trg_ForTheWin = CreateTrigger(  )
    call TriggerRegisterPlayerChatEvent( gg_trg_ForTheWin, Player(0), "-ftw", true )
    call TriggerRegisterPlayerChatEvent( gg_trg_ForTheWin, Player(1), "-ftw", true )
    call TriggerRegisterPlayerChatEvent( gg_trg_ForTheWin, Player(2), "-ftw", true )
    call TriggerRegisterPlayerChatEvent( gg_trg_ForTheWin, Player(3), "-ftw", true )
    call TriggerRegisterPlayerChatEvent( gg_trg_ForTheWin, Player(4), "-ftw", true )
    call TriggerRegisterPlayerChatEvent( gg_trg_ForTheWin, Player(5), "-ftw", true )
    call TriggerRegisterPlayerChatEvent( gg_trg_ForTheWin, Player(6), "-ftw", true )
    call TriggerRegisterPlayerChatEvent( gg_trg_ForTheWin, Player(7), "-ftw", true )
    call TriggerRegisterPlayerChatEvent( gg_trg_ForTheWin, Player(8), "-ftw", true )
    call TriggerRegisterPlayerChatEvent( gg_trg_ForTheWin, Player(9), "-ftw", true )
    call TriggerRegisterPlayerChatEvent( gg_trg_ForTheWin, Player(10), "-ftw", true )
    call TriggerRegisterPlayerChatEvent( gg_trg_ForTheWin, Player(11), "-ftw", true )
    call TriggerAddAction( gg_trg_ForTheWin, function ForTheWin )
endfunction

GUIWin
    Events
        Player - Player 1 (Red) types a chat message containing -ftw as An exact match
        Player - Player 2 (Blue) types a chat message containing -ftw as An exact match
        Player - Player 3 (Teal) types a chat message containing -ftw as An exact match
        Player - Player 4 (Purple) types a chat message containing -ftw as An exact match
        Player - Player 5 (Yellow) types a chat message containing -ftw as An exact match
        Player - Player 6 (Orange) types a chat message containing -ftw as An exact match
        Player - Player 7 (Green) types a chat message containing -ftw as An exact match
        Player - Player 8 (Pink) types a chat message containing -ftw as An exact match
        Player - Player 9 (Gray) types a chat message containing -ftw as An exact match
        Player - Player 10 (Light Blue) types a chat message containing -ftw as An exact match
        Player - Player 11 (Dark Green) types a chat message containing -ftw as An exact match
        Player - Player 12 (Brown) types a chat message containing -ftw as An exact match
    Conditions
    Actions
        Game - Display to (All players) the text: ((Player  + (String((Player number of (Triggering player))))) +  has won!)
        Wait 3.00 game-time seconds
        Player Group - Pick every player in (All players) and do (Actions)
            Loop - Actions
                Game - Victory (Picked player) (Skip dialogs, Skip scores)

Purpose
What this does, is displays the victor as a game/text message to everyone instead of using the dialog boxes to do so. And after a set period of time this is displayed, you'll be taken directly to channel or first screen after logon. There's no reason to let someone know they've won when the game text already shows that, there's no reason to show game scores which are designed for melee. The main point to this is to get everyone out of the game completely so that there isn't some annoying bastard AFK holding that game name for who knows how long.

It's shocking that this isn't used on just about every map as well as I haven't seen it used on any map.
