I never test on a public server, I have my own "crew" of testers, though if you say triggers are your thing, I will just go with that.
Survival/Timed is a bit... mehh

there isn't a huge difference between them.
Do
not upload a fix, instead update this map (and only when you think it can get approved, otherwise I will just reject it again).
Do
not upload other people's map: first of all, you need their permission to deprotect, edit and upload it (if you didn't get permission for one of those 3 things, you may not upload it).
It is called stealing and you will get banned for it, since there's a high anti-stealing policy on the hive.
Damage Formula:
(taken from my object editor tutorial, which is on another site).
Because of the lack of knowledge of the object editor, there are a lot of maps where a unit has "500-501" damage, or "500-499", while it should be "500-500".
It may seem a bit weird at first, but it's really easy... I will try to guide you through this so you can calculate the damage in a few seconds (it doesn't take longer than 10 seconds, for me at least).
You can see 3 damage data:
- Combat - Attack X - Damage Base (A)
- Combat - Attack X - Damage Number of Dice (B)
- Combat - Attack X - Damage Sides per Die (C)
I have given letters to each data, to make it look a bit better.
The rough formula is:
(A+B)-(A + (B * C))
Of course, nobody feels like doing this every time...
The first number of the damage is very simple, let's say we want 50-60 damage.
The first number is 50, so we need to create 50...
A = 49
B = 1
49 + 1 = 50
Everyone agrees with me here I hope.
Now the second damage, we have already defined A and B, so the only thing left is C.
I have made it really simple for us, since I've made B = 1.
The formula now says:
50-(A + (1 * C))
OR
50-(a + c)
Very simple: 49 + 11 = 60, so C needs to be 11...
Overview:
- Combat - Attack X - Damage Base (49)
- Combat - Attack X - Damage Number of Dice (1)
- Combat - Attack X - Damage Sides per Die (11)
With this we have 50-60 damage.
To get simple damages, like 50-50, 45-45, 100-100, etc...
You just need to set A = (damage - 1) and B and C = 1.
Then you get something like:
- Combat - Attack X - Damage Base (49)
- Combat - Attack X - Damage Number of Dice (1)
- Combat - Attack X - Damage Sides per Die (1)
Which gives 50-50 damage.
That's all there is to it, to make it easy for yourself: try to set B=1 as much as possible.
I don't do it myself, but that's because my math isn't bad...
