[Trigger] Searching for a Trigger to make this Unique Spawn System

[Blackrockorc]

when i do test runs of my game, planet of the orcs. it seems with waves of them it gets boreing cuz there locations are pretty preset. I came up with an idea for a spawner but someone said its too complex, might be impossible.
This is basically the layout no details missed. i will credit whoever can make it.

On the map there are troll's, these guys are who people play every1 gets one troll.

I want a spawn trigger that will spawn this cargo container(a unit). i need for the cargo container to drop in from the sky with a slow descent to the ground from ther it will spawn orc units in a feed fasion(several come out at a time). It should drop about 1000-2000 feet from the targeted troll;with a 1% chance to drop on trolls location.

JaiJaibinx already did the feed spawner for the map just need to kno how i would connect it to the part, with the part that hasnt been created
This the feed trigger

• The Coming Of the Horde
  • Events
    • Time - Every 300.00 seconds of game time
  • Conditions
  • Actions
    • Set TempGroup = (Units in (Playable map area) matching (((Owner of (Matching unit)) Equal to Player 11 (Dark Green)) or ((Owner of (Matching unit)) Equal to Player 12 (Brown))))
    • Set TempGroup2 = (Units in (Playable map area) matching (((Matching unit) belongs to an enemy of Player 12 (Brown)) Equal to True))
    • For each (Integer A) from 1 to 35, do (Actions)
      • Loop - Actions
        • Set Spawn_Point2[1] = (Random point in SpawnRegions2[(Random integer number between 1 and 2)])
        • Unit - Create 1 Grunt for Player 12 (Brown) at Spawn_Point2[1] facing Default building facing degrees
        • Unit - Order (Last created unit) to Attack (Random unit from TempGroup2)
        • Unit - Create 1 Grunt for Player 11 (Dark Green) at Spawn_Point2[1] facing Default building facing degrees
        • Unit - Order (Last created unit) to Attack (Random unit from TempGroup2)
        • Custom script: call RemoveLocation (udg_Spawn_Point2[1])
        • Custom script: call RemoveLocation (udg_Spawn_Point2[bj_forLoopAIndex])
        • Wait 0.00 seconds
    • Custom script: call DestroyGroup(udg_TempGroup)
    • Custom script: call DestroyGroup(udg_TempGroup2)

Good Luck if any even decides to attempt it for me, will credit you in my map

ummm ok nothing is impossable if you put your mind to it. xD

But Heres What I Would Do
Event W.e spawns the container
Actions Create A Container At A Random Point Within 1000,w.e Of Troll
Anamation Set Height Of (Entering Unit) To 1500

If Than Else

If Height Of Entering Unit Greater Than Or Equal To 1

Than Actions

Loop Actions

Set Height Of Entering Unit To Current Height - 25

Else Action

Set Triggering Units Height To 0
Set Spawn Point To Postion Of Triggering Unit.

Than Continue The Trigger With Spawns From The Point. You May Need To Edit.
