i'm afraid it's the same old story people won't have got the new army book yet or won't have played them yet so don't have the experience of what does what against the new killer army.
i remember (back in the day) when the last lizardmen book came out and they were the ''top army to beat'' at tourneys. a guy copy pasted the list that someone else used came up to our club and i played him with my empire cavelry army and took his uber killer list apart, though to be honest 10 cav regts will pretty much do that to anyone. now thats not to say it's a smash all list, it's just that he'd never come against a list like it before so didn't have a coping mechanism for it.
people will develop ways of dealing with them in time or a new army book will come out and the ogres will drop off from being the new killer army until the next time their army book is re-done.
i'm afraid that it's one of the reasons i drifted away from fantasy, i got bored of playing the uber death lists all the time.
