I agree that MikroTik could do more to make home or small office users happy. It's not so long since they started to target these groups and IMHO they're still not very dedicated to it. So yeah, there is room for improvement.
But it's not like they're promising something they don't give you in the end. Before you buy anything, you can check
wiki where you can see everything RouterOS can do. You can even download complete version of RouterOS to play with in virtual machine for free (except for wireless interfaces). If you feel cheated or anything like that, I don't think it's deserved.
And btw, this is user forum. If you want to communicate with MikroTik, you should write to their support.
