the_arctic_one, he is likely referring to Wobbuffet's personal style of playing: forking your opponent using Encore and Shadow Tag, then pretty much always being able to respond in the Wobbuffet's player's huge advantage with either free turns or a Counter/Mirror Coat for a quick KO. This pretty much requires little to no prediction to pull off.
I disagree that Wobby was banned just for that. It required his rather large durability to be able to pull it off effectively. I don't think you'll have an easy time finding many good OU Pokemon who aren't capable of downing Wynaut in 2 hits, with the exception of Blissey, which heavily reduces the "mindless" window Wobbuffet has (it can't switch into any attack now, and it needs to predict right instead of Encoring if it wants to Counter/Mirror Coat something that 2HKOs it).
