You must have missed the reign of Grubby then, lol. But yeah, there's very little UD can do vs Orc, and Blizzard obviously never had any intentions of fixing it. I remember Lucifer had a couple good games vs Orc when he went Dread Lord first on certain maps to get the sleep->surround, but it was really just a cheese strat at best that worked best on extremely small maps or close spawns. Ted's fast crypt fiend build was, iirc, the best attempt UD had and it still had an incredibly low win rate.
Look up Hitler's reaction to Blademaster (at work right now, can't link). It's funny because it's true. It represents how I felt as an UD player.
