Yeah that's controlling your units. Apart from automatically forming into a nice formation (like in FA) do you want units to automatically dodge artillery shells, automatically dodge slow projectiles, and automatically kite?
of course not, but i don't want that with perfect (or nearly perfect) micro for example 5 levelers can take out 15 levelers that are not micromanaged, witch is possible at this time (and i think even more). if you want to kill larger groups with less units then you should need some different like 3 t2 artys and 5 t2 tanks to kill 12 t2 tanks thanks to the advantage of your formation where you can fire because of range a little more early. but with same units micro shouldnt make that mutch difference linke now.
correct. if you get an advantage of dunno 20% with absolut perfect micro (so players achive 10-15% if they are good in reality) there is no problem, but the actual 300% or more is simply too mutch.
