but there are two types of balance on RTS games
1- Unit vs. unit balance
2- general consensus balance
in the first scenario.. all the units are compareably priced to their damage, no unit has a specific goal, they all just have "types" of ammo, "types" of defense, and sometimes, slightly a "type" of attack method. This causes units to be built specifically to counter outer units to win, its balanced only to the aspect that you can win when you counter your opponent correctly. Simmilar games to this: Starcraft, Warcraft, Warhammer 40k.
In the second scenario, units are designed as a "type" of unit, offense, defense, scouting, etc. and they have tailored abilities to do so, defensive units are tougher, and slower, offensive have either reduced range with increased speed and armor, or increased range, with drastically reduced armor. Unit costs are balanced according to a units effectiveness, with a general "cheaper" trend towards defensive units. There really are no "specific" weapons that are better at beating "specific" other units... so what happens is a good balance of units and good TACTICAL strategy to win. simmilar games are Command & Conquer, Generals, KKnD, and some of the smaller "not-so-popular" RTS games...
What this means? It takes more skill and micromanegement to play Type 1, its harder to beat a good player in type 1, its harder to be creative in type 1, and its easier to memorize a "build order" in type 1. Most of these are good things in an RTS, morons can't beat the wiser, etc. But in type 2, you aren't gonna have to be as nit-pickey with which units are used against which individual units, but rather have to consider attack and defense methods, rather than knowing "what works best" you have to "out strategize" your opponent to win. And a RTS that requires STRATEGY to win over expierence... is more fun in my book.
I've just been trying to get people to push towards option 2, you, as a skilled player in its current state, option 1, are rejecting the change because, YES it is a big change, you'll have to think differently, hell.. think at all... not just "know what to do." Darn if I am trying to make everyone think TACTICALLY.

thats all I have to say for awhile.
