First of all,
Thank you for your that review. It really means a lot to me
In the current version, the High-level creeps start spawning at 20 or 30 minutes (30 most likely)
I fixed this in 1.08.
Creeps get stronger randomly every few seconds

(+1HP or +1 damage or +1 movement speed, etc..)
I'm also giving creeps special abilities.
Also, assists have been added (Thanks to the awesomeness that is ASS 4.3.0.0)
-swap commands will be added.
-switch will be added too.
I'm going to redo most of the heroes.
Some of them are imbalanced and others are just too weak :/
I'm going to add a tips system for beginners.
And in the future, I will add a feature that lets an AI player take over if a player leaves ;D
Also, the deny-ally thing is a real surprise to me :c
I have a jass trigger for it that doesn't let you deny your enemies unless they have less than 5% HP D:
The terrain is being redone too.
I haven't started on it though.
I'm going to add alternative goals to the map too

This way a failing team still has a chance to win and the leading team gets more vulnerable and vulnerable in one area the stronger they are.
The Base-dereg thing says "Killed by Neutrals" because I was making the Lich King damage you

I'm rewriting a few systems and including a "DeathType" struct.
Leaver items/gold will be given to you in the next version.
And the abilities aren't all standard at the moment

Out of the 56 spells, there are about 30 or 40 triggered ones.
I'm going to trigger them all in the next version.
I'm also going to add a "Quick tutorial" for beginners.
It'll start a cinematic that teaches you the basics of your hero and gives you tips too.
You can exit at any time and get back into the game.
I'll be sure to set your level so that it's equal to the average level of all heroes on your team.
1.08 is going to be a huge update.
