Heretic of The Seventh Circle
The martial classes were for people who didn't want the full option overload of 4e. I'll almost certainly never play either a Slayer or a Scout - but I have seen players who were massively more comfortable with them than they are with classic 4e characters. The big problem with Essentials is that the wizard in it was the mage and not the Elementalist; simplified classes are a good thing as long as we also have the full versions.
The problem there is that the scout and slayer and the like could have had simple powers that could optionally, as purely a buying decision, be swapped with earlier powers, and a person making a scout would have no added overhead. They just play it as presented. While I, on the other hand, could grab regular ranger or fighter powers because I like that choice complexity. Basically, the stupid feat they put in should have just been how the classes worked.
