To be honest Eskimo, you have a fair point about people over-using undead and orcish lord etc. But that in itself is the essence of warcraft mod. Finding counters and way to protect yourself from other people. Necklace of Immunity is $1200 and you can't buy it every round. So you have to sort of see when it is needed, and you can also buy more health, use a race that blocks ultimates or stay away from orcs and kill them from range.
Warcraft mod isnt fair. But to some extent it should be controlled. There are races that are ridiculously overpowered (of which some need to be removed), and some that are fairly powerful and annoying (but can be easily countered and don't need removing).
But the fun thing about it is that there is a way to combat everything, no matter how overpowered they are. If you want to get 30-0 every map, go to a public server which doesn't have crazy things flying around everywhere
