Attempting to "blame" dual wielding on 4e is misguided. Dual weilding large weapons has been around since at least 2e (I can't offhand remember if it was an option for 1e PCs or limited to races like drow)- and with a good dex was a actually a superior option in 2e.
Another gross misrepresentation of what was said. Where did I "blame" dual-wielding on 4e? Also, large weapons were not allowed to be dual-wielded in 2e, at least through the handbooks. There were strict penalties for dual-wielding and the off-hand weapon needed to be small. The Fighters Handbook opened things up a bit with style specializaton but not to large weapons. The most damaging combo you could generally use was a Long Sword/Hand Axe combo.
