Well, it's all about taste and what they like. Even if SC2 gets bad reception for melee, we can still look forward to the possibilities with the map editor.
It is not ordinary to beat and not to lose at all from orc, hu and elf and to lose from low skilled undeads. It is not ordinary a win vs ud to be 40-50 mins when you have advantage and 70 food vs 40-50 and to need 3-4 scrolls and many battles to win even with expand. Undead is just imba. When the difference between playing vs the other 3 races even in vs-race-% is so huge compared to vs ud, that's the damn imba race. You play vs fiends - either surround fiends or no way to kill fiends. While you surround fiends you mass lose militia ciz w/o them foots die fast. In late game DK gets more imba than any other hero in the game. Even with lich, 1 nova makes you lose if you fight with foots and am vs dk lich and ghouls, not to say fiends where they just need to shoot once and then the missiles kill no matter how far the foot is.
My point: especially if you read some news abou incoming war3 patch are, if this >>>>>
crap<<<<<<< happens, I leave war3 Ladder/games vs ud/ on the double, I won't even wait for SC2. Coz it's not ordinary to lose only from good other 3 races and to lose from some noobs whoz only strat is mass fiends and the only micro is coil fiends... Coz the rest 3 races are free wins but with ud even a newb can win, well not a total newb but still a newb. Upgraded knights (attack and armor + hp) in late game vs UNUPGRADED aboms and fiends and lvl 5 and 4 to dk and lich die like peasans... no even vs fiends the die so fast and if you don't have micro to save them, lately I do save them - GG, talk about upgraded knights vs unupgraded aboms ... with disease. And if you don't have scrolls, GG dk becomes lv l5 and mass nukes, knights die like peasants... Ordinary??????
So my point is at least not have 1 race that is wayy imba compared to the other 3 or 2 (in SC) races.
